A hydraulic hand pump is ideal for emergencies, for example when the power supply has failed and urgent opening or closing is required. Hand-operated hydraulic pumps are therefore independent of fossil fuels or electricity. All you need is your own muscle power to operate the hydraulic hand pump.

Our MP series hydraulic hand pumps are designed for direct use with hydraulic cylinders. They allow manual, powerful, and precise movement of cylinders in mobile or stationary systems. The double-acting function ensures that the hydraulic oil is pumped during both the forward and return strokes of the operating lever – ideal for smooth and efficient cylinder control. All models are single-acting and can be mounted directly on a tank.

 

Hand Pumps – Frequently Asked Questions

What is a single-acting hand pump with double stroke?

A single-acting hand pump with double stroke is a manual pump that delivers hydraulic oil during both the forward and return stroke of the handle. This means that with every handle movement, regardless of direction, oil is pumped into the system, which significantly increases the pump’s efficiency and reduces working time.

Which hand pump models are available and how do they differ?

We offer two main models:

  • MPKP model: This model is equipped with a pressure relief valve that protects the hydraulic system against overpressure. The pressure can be adjusted within the range of 40 to 300 bar. The factory default setting for the relief valve is 150 bar, unless otherwise specified.
  • MP model: This model does not have a pressure relief valve. Instead, it features a G3/8" port.

Both models are equipped with an unloading valve.

What reservoir capacities are available for the hand pumps?

The hand pumps can be supplied either without an oil reservoir or with integrated reservoirs in various sizes:

  • 3 litres
  • 5 litres
  • 8 litres
  • 10 litres
  • Without reservoir (for external tank connection)

What is the geometric displacement per double stroke?

The geometric displacement per double stroke is 25 cm³ per double stroke. This indicates the amount of oil delivered during one complete forward and return movement of the handle. This capacity enables efficient filling of hydraulic systems.

Which type of hydraulic fluid is recommended and what filtration level is required?

Mineral oil according to ISO 6743/4 is recommended as the hydraulic fluid. The required filtration level is 25 µm to ensure system cleanliness and to support optimal pump performance and service life.

What is the purpose of a pressure relief valve in MPKP pumps?

The pressure relief valve (present only in MPKP pumps) serves to protect the hydraulic system from overpressure. When the system pressure exceeds a preset value, the valve opens and directs excess oil back to the reservoir, preventing damage to the system. The adjustment range is between 40 and 300 bar.

What is the function of the unloading valve?

The unloading valve is present in both pump types (MPKP and MP). It allows pressure release in the system, thereby lowering a load. The standard unloading valve length is 600 mm for the MP pump and 900 mm for the MPKP pump.

What information is important when ordering a hand pump?

The order code is crucial, as it specifies the desired pump configuration. This code includes information about:

  • The model (MPKP with or MP without pressure relief valve)
  • The reservoir capacity (e.g., 3, 5, 8, 10 litres or without reservoir)
  • For MPKP pumps, the desired pressure setting of the relief valve

If no pressure setting is specified, the factory default pressure is 150 bar.

What advantages does the double stroke feature offer compared to conventional hand pumps?

The double stroke feature offers several key advantages:

  • Double efficiency: Oil is delivered in both stroke directions
  • Reduced working time: Fewer handle movements for the same delivery volume
  • Less fatigue: More efficient operation during extended use
  • Smoother oil flow: More continuous oil delivery in the system

When should I choose an MPKP pump and when an MP pump?

The choice depends on your safety requirements:

  • Choose an MPKP pump if you need an integrated safety system. The pressure relief valve automatically protects against overpressure and is ideal for applications where excessive pressure could be dangerous or damaging.
  • Choose an MP pump if you prefer external pressure control or require a simpler, more cost-effective system. The G3/8" port allows flexible connection options.

How do I choose the right reservoir size for my application?

The reservoir size depends on your application:

  • 3–5 litres: For smaller, occasional applications and mobile use
  • 8–10 litres: For larger systems or frequent use
  • Without reservoir: If you already have an external tank or require maximum flexibility in system integration

Consider your hydraulic system’s volume and usage frequency.
