Electric Pumps – Frequently Asked Questions

What are electric pumps and how do they work?

Electric pumps are electrically powered pumps that move hydraulic fluids in a targeted manner. They use electric motors as direct drives and operate either according to the displacement principle (e.g. piston or diaphragm pumps, where a defined volume is mechanically displaced) or according to the principle of kinetic energy (e.g. centrifugal pumps, where the fluid is accelerated by rotating movement and kinetic energy is converted into pressure).

The DC motor-pump units offered in the Hydromot Shop are examples of such pumps, using a gear pump to transport hydraulic fluid.

What are the advantages of electric pumps?

  • High efficiency due to direct electric drive
  • Low-maintenance and reliable when properly installed
  • Wide selection of models and materials for nearly any pumping task
  • Simple and precise control using variable frequency drives (VFD)

These characteristics make electric pumps indispensable in many industries.

What materials are electric pumps typically made of and what sizes are available?

Electric pumps are made – depending on application and medium – from various materials:

  • Stainless steel (e.g. AISI 316L for high corrosion and temperature resistance)
  • Polypropylene or PVDF for chemical resistance
  • Aluminium for lightweight design

Sizes range from small drum pumps with lengths of 200–3000 mm to large-scale industrial units.

Where are electric pumps and hydraulic power units typically used?

  • Electric pumps and hydraulic power units serve as central supply systems in mechanical engineering, plastics processing, lifting and hoisting equipment, presses, and mobile applications such as tail lifts or fan drives.

How are hydraulic power units constructed and what types exist?

A hydraulic power unit typically consists of:

  • Drive unit (e.g. electric motor, petrol or diesel engine)
  • Hydraulic pump (e.g. gear, axial piston or vane pump)
  • Hydraulic tank

The drive unit is usually connected to the pump via a coupling. In compact units, motor, pump and tank are connected by a central flange, which can also accommodate valves.

Types: compact units, standard units, submerged units.

What criteria are crucial for selecting the right electric pump?

  • Medium and material compatibility
  • Required flow rate (l/min, m³/h) and pressure (bar)
  • Temperature and solids tolerance
  • Operating mode (continuous or intermittent)
  • Size and installation conditions (e.g. submersible, drum, stationary)

What affects the service life of electric pumps and what maintenance is important?

Service life depends on maintenance, material quality and operating conditions. Stainless-steel pumps can last for decades with proper care.

Important maintenance measures:

  • Regular inspections for wear and leaks
  • Cleaning of deposits and dirt
  • Lubrication of moving parts
  • Monitoring of impellers
  • Predictive maintenance using sensors and data analysis
