Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 51% of the average value of its portfolio.

Strategy [Heading]	rr_StrategyHeading	<span style="color:#000000;font-family:Arial;font-size:8.5pt;font-weight:bold;margin-left:0%;">What are the Fund’s Main Investment Strategies?</span>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund is a non-diversified portfolio of Federated Hermes Managed Pool Series. The Fund pursues its investment objective by investing primarily in equity securities of companies based in countries outside the United States, consisting principally of high dividend-paying stocks with dividend growth potential. The Fund is designed to purchase securities required for the high dividend-paying international stock investment strategies (“International Dividend Strategies”) that cannot be efficiently held individually in Eligible Accounts, but can be effectively held in a pooled vehicle, such as a mutual fund. Federated Equity Management Company of Pennsylvania (the “Adviser”) believes a strategic emphasis on high dividend-paying stocks can enhance performance over time. In addition, the Adviser seeks to enhance investment results by focusing on stocks with both the potential for future dividend growth and current dividend-oriented characteristics. The Adviser believes that this is achievable while targeting less risk than the broader market.As a fundamental policy, the Fund will concentrate its investments by investing more than 25% of the value of its total assets, in the aggregate, in one or more of the following groups of industries: banks; telecommunication services; insurance; utilities; and energy.The Fund’s security selection process involves prioritizing stocks based on appropriate fundamental criteria. Those companies that rank as highly attractive in the prioritization process are closely scrutinized for inclusion in the portfolio using bottom-up fundamental proprietary research. The Fund may use derivative contracts (such as forward contracts) to manage or hedge the Fund’s currency exposure. There can be no assurance that the Fund’s use of derivative contracts will work as intended. Derivative investments made by the Fund are included within the Fund’s 80% policy (as described below) and are calculated at market value.The Fund generally invests in large-cap or mid-cap stocks (which are generally defined as of the date of this prospectus as stocks of companies with market capitalization above $10 billion and $3 billion, respectively) and may also hold depositary receipts and real estate investment trusts. The Adviser anticipates that normally the Fund will invest in companies based in developed countries, although to a lesser extent, the Fund may also invest in foreign companies based in emerging markets.The Fund will normally invest its assets so that at least 80% of its net assets (plus any borrowings for investment purposes) are invested in dividend-paying securities. The Fund will notify shareholders at least 60 days in advance of any change in its investment policy that would enable the Fund to normally invest less than 80% of its assets (plus any borrowings for investment purposes) in dividend-paying securities.
Risk [Heading]	rr_RiskHeading	<span style="color:#000000;font-family:Arial;font-size:8.5pt;font-weight:bold;margin-left:0%;">What are the Main Risks of Investing in the Fund?</span>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund’s returns include:■  Stock Market Risk. The value of equity securities in the Fund’s portfolio will fluctuate and, as a result, the Fund’s Share price may decline suddenly or over a sustained period of time. Information publicly available about a company, whether from the company’s financial statements or other disclosures or from third parties, or information available to some but not all market participants, can affect the price of a company’s shares in the market. Among other factors, equity securities may decline in value because of an increase in interest rates or changes in the stock market. Recent and potential future changes in industry and/or economic trends, as well as changes in monetary policy made by central banks and/or their governments, also can affect the level of interest rates and contribute to the development of or increase in volatility, illiquidity, shareholder redemptions and other adverse effects (such as a decline in a company’s stock price), which could negatively impact the Fund’s performance.■  Mid-Cap Company Risk. The Fund may invest in mid-capitalization (or “mid-cap”) companies. Mid-cap companies often have narrower markets, limited managerial and financial resources, more volatile performance and greater risk of failure, compared to larger, more established companies. These factors could increase the volatility of the Fund’s portfolio, performance and Share price.■  Large-Cap Company Risk. The Fund may invest in large capitalization (or “large-cap”) companies. In addition, large-cap companies may have fewer opportunities to expand the market for their products or services, may focus their competitive efforts on maintaining or expanding their market share, and may be less capable of responding quickly to competitive challenges. These factors could result in the share price of large companies not keeping pace with the overall stock market or growth in the general economy, and could have a negative effect on the Fund’s portfolio, performance and Share price.■  Risk Related to Investing for Dividend Income. There is no guarantee that the issuers of the stocks held by the Fund will declare dividends in the future or that, if dividends are declared, they will remain at their current levels or increase over time. Because a dividend is always a positive contributor to total return, dividend paying stocks are typically less volatile than non-dividend paying stocks. Accordingly, the Fund’s performance may lag behind the general market when dividend paying stocks are out of favor.■  Risk of Foreign Investing. Because the Fund invests in securities issued by foreign companies and national governments, the Fund’s Share price may be more affected by foreign economic and political conditions, taxation policies, and accounting and auditing standards than would otherwise be the case.■  Risk of Investing in Depositary Receipts and Domestically Traded Securities of Foreign Issuers. Because the Fund may invest in American Depositary Receipts (ADRs) and other domestically traded securities of foreign companies, whether in the United States or in foreign local markets, the Fund’s Share price may be more affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case.■  Currency Risk. Exchange rates for currencies fluctuate daily. Accordingly, the Fund may experience volatility with respect to the value of its Shares and its returns as a result of its exposure to foreign currencies through direct holdings of such currencies or holdings on non-U.S. dollardenominated securities.■  European Union and Eurozone Related Risk. A number of countries in the European Union (EU), including certain countries within the EU that have adopted the euro (Eurozone), have experienced, and may continue to experience, severe economic and financial difficulties. Additional countries within the EU may also fall subject to such difficulties. These events could negatively affect the value and liquidity of the Fund’s investments in euro-denominated securities and derivatives contracts, securities of issuers located in the EU or with significant exposure to EU issuers or countries.■  Custodial Services and Related Investment Costs. Custodial services and other costs relating to investment in international securities markets generally are more expensive than in the United States. Such markets have settlement and clearance procedures that differ from those in the United States. The inability of the Fund to make intended securities purchases due to settlement problems could cause the Fund to miss attractive investment opportunities.■  Sector Risk. Because the Fund may allocate relatively more assets to certain industry sectors than others, the Fund’s performance may be more susceptible to any developments which affect those sectors emphasized by the Fund.■  Risk of Investing in Emerging Market Countries. Securities issued or traded in emerging markets generally entail greater risks than securities issued or traded in developed markets. Emerging market countries may have relatively unstable governments and may present the risk of nationalization of businesses, expropriation, confiscatory taxation or, in certain instances, reversion to closed market, centrally planned economies.■  Liquidity Risk. The equity securities which the Fund invests may be less readily marketable and may be subject to greater fluctuation in price than other securities.■  Risk of Investing in Derivative Contracts. Derivative contracts involve risks different from, or possibly greater than, risks associated with investing directly in securities and other traditional investments. Specific risk issues related to the use of such contracts include valuation and tax issues, increased potential for losses and/or costs to the Fund and a potential reduction in gains to the Fund. Each of these issues is described in greater detail in this Prospectus. Derivative contracts may also involve other risks described in this Prospectus, such as stock market, currency and liquidity risks.■  Technology Risk. The Adviser uses various technologies in managing the Fund, consistent with its investment objective and strategy described in this Prospectus. For example, proprietary and third-party data and systems are utilized to support decision making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance.■  Risk of Non-Diversified Fund. The Fund is non-diversified. Compared to diversified mutual funds, it may invest a higher percentage of its assets among fewer issuers of portfolio securities. In certain situations, being non-diversified may reduce the Fund’s credit risk by enabling it to avoid investing in certain countries, regions or sectors that exhibit above average credit risk. However, being non-diversified may also increase the Fund’s risk by magnifying the impact (positively or negatively) that only one issuer has on the Fund’s share price and performance.■  Concentration Risk. Because the Fund will be concentrated in certain groups of industries, it may be subject to more risks than if it were broadly diversified across additional industries and groups of industries of the economy. General changes in market sentiment towards a group of industries may adversely affect the Fund, and the performance of such groups of industries may lag behind the broader market as a whole.■  Real Estate Investment Trust Risk. Real estate investment trusts (REITs) carry risks associated with owning real estate, including the potential for a decline in value due to economic or market conditions.■  Risk Related to the Economy. The value of the Fund’s portfolio may decline in tandem with a drop in the overall value of the markets in which the Fund invests and/or other markets. Economic, political and financial conditions, industry or economic trends and developments or public health risks, such as epidemics or pandemics, may, from time to time, and for varying periods of time, cause the Fund to experience volatility, illiquidity, shareholder redemptions, or other potentially adverse effects.The Shares offered by this Prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.
