Pumps

Selfpriming Centrifugal Pumps for liquids with solids:

  • Horizontal one-stage centrifugal pumps with open impellers handling fluids with solids with a diameter up to 75 mm.
  • The special design makes the "S" series a quick self-priming pump. Foot valves are not necessary. The pump self-primes automatically to depths of 7.5 m.
  • With easily replaceable steel wear-plates, a high resistance to abrasion is guaranteed.
  • All pumps are equipped with externally lubricated mechanical seals. Lubrication prevents damage during dry-running and stops leaks of air or liquid along the shaft.
  • The "S" series pumps can be supplied in several kinds of materials (cast iron, bronze, stainless steel) for various types of application.
  • We build special features according to our customer’s desires.

Selfpriming Positive Displacement Rotary Pumps for liquids of any viscosity:

  • The internal gear pumps of the "R"-series are positive displacement rotary pumps. The capacity is directly proportional to the rotation speed and virtually independent of the pressure.
  • The flow is smooth and non pulsating in either direction of rotation.
  • Depending on the application, the pumps will be delivered with packed gland or a mechanical seal, or in special sealless execution with magnetic couplings.
  • The internal gear pumps of the "R"-series are manufactured in stainless steel and cast iron. If desired, special materials and material combinations can be used.
  • The special construction with possibility for lock rings for precise rotor positioning and pump casing with a heating jacked gives a high performance.

Magnet Drive Pump:

Magnet drive pumps have long been the preferred option for handling hazardous or environmentally threatening liquids in safety critical applications in the chemical, petrochemical, pharmaceutical and processing industries.

This is because they do not leak. Magnet drive pumps combine an exceptionally long-term reliability with minimum maintenance requirements.

With the introduction of ever stricter environment legislation, product liability laws and health and safety regulations, more and more customers are demanding leak-free process environments.

The principle of magnet pumps is very simple:

A magnet drive pump allows the impeller to be driven without any physical contact with the motor.

The pump shaft and rotor are immersed in the process liquid and contained within a non-magnetic shroud through which the magnet power is transmitted.

There are two types of sealless magnetically drive pump designed for different applications:

The first type of magnetically driven pumps uses powerful "Rare Earth Magnets", mounted within the rotor to provide an inner magnetic ring and direct attraction spins the impeller at the same speed as the outer magnetic ring coupled to the prime mover. Though extremely efficient, these synchronous drive pumps are limited to a maximum temperature of 260ºC.

The second type of magnetic drive uses the "Torque Ring" drive coupling, in which the torque ring is drawn after the outer magnet ring at a slightly slower speed. The design is ideally suited to high temperature operations; the Torque Ring pumps can operate uncooled with liquids up to 450ºC.
