Elika low noise, low pulsation helical gear pumps

ELIKA® HELICAL GEAR PUMPS »

The low noise, high efficiency, low pulsation gear pump reduces noise level by an average of 15 dBA. The helical profile of the gears reduces pressure oscillations and vibrations produced by the pump, transmitted to the other components, reducing the noise of the hydraulic system. Axial forces induced by the helical teeth are optimally balanced in all operating conditions by the axial compensation system integrated in the pump cover.

vane pumps

VANE PUMPS »

All the components subject to wear are contained in a cartridge unit that can be easily removed for inspection and/or replacement without disconnecting the pump from the circuit, drastically reducing expensive machine down time.

Self priming volumetric screw pumps

SCREW PUMPS »

These screw pumps are volumetric self-priming screw pumps suited to handle oils and liquids with a minimum lubricating quality. The design simplicity makes these screw pumps intrinsically reliable and efficient.
The accurate hydraulic balance and the special profile of the screw thread guarantee a continuous flow with minimum pulsations and turbulance, resulting in extremely low noise levels even at high rotational speed.

Low speed, high torque hydraulic motors

LOW SPEED, HIGH TORQUE (LSHT) HYDRAULIC MOTORS »

Fixed displacement, conform to ATEX directive 94/9/EC, up to 50 rotational direction changes per second, high starting torque, total efficiency up to 96%. Suitable for use as pumps with boosted system. Due to the low amount of revolving mass, the rotational direction can be quickly changed.

Gear motors convert hydraulic pressure and flow into torque and angular displacement, rotary mechanical power.

GEAR MOTORS »

Gear motors convert hydraulic pressure and flow into torque and angular displacement, rotary mechanical power, applied to a load via the shaft. Hydraulic fluid is moved into the motor causing the matched gear set to rotate. One of the gears is connected to the motor output shaft so producing the rotary mechanical power.
A complete range of integrated relief valves and anti-cavitation valves to suit a wide range of applications are available as standard.

Pressure Intensifiers; high pressure obtained from low pressure hydraulic power sources. Achieve high pressure from low pressure hydraulic power sources. Advantageous where space is of a premium in existing or new hydraulic circuits. See further details here . . .
motor-pump-set
A motor pump set consists of a prime mover such as a petrol / diesel engine, electric, hydraulic, or air motor connected to a fluid pump / gas pump via a coupling or a bellhousing and coupling combination. The advantage of using a bellhousing being that full concentricity is maintained between the prime mover and the connected pump, thus negating the potential of an early coupling failure due to shaft to shaft misalignment.
