Single stage chemical standard pump according to ISO 2858 with magnetic coupling

The type NML is a standard chemical pump PN16 according to ISO 2858 with magnetic coupling.

Adapted from the characteristic diagram sizes and the requirements of the operator, it is graded so that the best possible efficiency is achieved.

The pump has a permanent magnet coupling, and the containment shell hermetically seals the fluid to the outside.

An internal circulation current dissipates the heat generated by the eddy current losses.

The bearing of the pump shaft is carried out in SiC plain bearings, the drive shaft is mounted in permanently grease-lubricated roller bearings. Wear rings are standard on the suction and pressure sides.

The axial thrust compensation is done by relief holes, back buckets or other measures.

In addition to the standard version, the following special constructions are available:

• pump housing with heating jacket
• version with open impeller and wear disc
• inducer

Self-priming, single or multi-stage centrifugal pump with shaft seal, lubrication: grease

The type HZS is a self-priming, single or multi-stage centrifugal pump with shaft seal.

The venting works on the principle of a side channel pump. The liquid present in the pump forms when starting with the amount of air present in the suction line, a liquid – gas mixture, wherein the existing air content is conveyed by the vent in the discharge nozzle. Due to the pressure-side arrangement of the venting stage, a complete venting of suction line and pump body is ensured.

To achieve low NPSH values, the suction stand is designed as an inlet spiral and the suction side impeller with an enlarged inlet cross section.

The axial thrust compensation takes place through relief boreholes and throttle gaps, wear rings are standard on the suction and pressure sides. The bearing of the pump shaft takes place in a cylindrical ball bearing and a double-sided angular contact ball bearing.

The pump can be operated both in the direction of rotation right and left.

Single or multi-stage side channel pump with permanent magnet coupling, set up horizontally

The type SCM is a single or multi-stage self-priming horizontal side channel pump. In addition to the self-priming ability side channel pumps have the advantage due to their high-pressure coefficient, with the promotion of small flow rates against relatively high-pressure levels, to work more economically than normal centrifugal pumps.

Due to the axial suction port and the upstream radial impeller, the SCM type achieves low NPSH values. The steps are sealed off from the atmosphere by chambered O-rings. The bearing of the pump shaft takes place in Sic plain bearings, on the drive side are permanently grease lubricated roller bearings arranged.

The pump has a permanent magnet coupling, and the containment shell hermetically seals the fluid to the outside. An internal circulation current dissipates the heat generated by eddy current losses.

Gear pump with permanent magnet coupling (mechanical coupling)

The type GML is an internal gear pump with magnetic coupling. The pump has only two moving parts, the impeller and the rotor.

In this case, the feed wheel is taken from the driven rotor.

The delivery liquid is drawn into the remaining free space between the tooth flanks of the delivery wheel and the rotor. The crescent-shaped sickle opens up the gaps between impeller and rotor, while the fluid is moved in pressure side. It creates a uniform flow rate without pulsation. The pump is always equipped with an easily adjustable safety valve (bypass).

The pump has a permanent magnet coupling, and the containment shell hermetically seals the fluid to the outside. An internal circulation current dissipates the heat generated by the eddy current losses.

The bearing of the pump shaft is carried out in SiC plain bearings, the drive shaft is mounted in permanently grease-lubricated ball bearings. The position of the nozzle is both angled and opposite possible.

Volute casing submersible pump according to ISO 15783 with magnetic coupling

The type NMT is a spiral casing submersible pump with shaft seal according to the principle of the two-pipe pump, i. separate shaft sealing tube and pressure tube.

The hydraulic pump part is arranged in the container or in the pumped medium.

The connection is made by a multi-level shaft and pipe string. The bearing of the pump and drive shaft takes place in plain bearings. This allows diving depths of up to 6m.

The pump has a permanent magnet coupling, and the containment shell hermetically seals the fluid to the outside.

The direct mounting of the drive motor eliminates additional bearings and the mechanical coupling.
