HPS Screw pump

Features

Screw pumps of the HPS range are canned pumps. Their ideal area of application is closed high-pressure circuits within hydraulic process engineering systems. Here the HPS represents a genuine, low-price alternative to the centrifugal pump without stuffing box. HPS pumps are not self-priming, so the pump circuit must be well vented.
HPS4100: screw pump for a max. permissible operating pressure of 100 bar
HPS4200: screw pump for a max. permissible operating pressure of 200 bar

Advantages

  • Canned pump: hermetically sealed and requires by and large no maintenance
  • For operating pressures of up to max. 100 resp. 200 bar
  • Carbon graphite axial and radial bearings: with the pump in operation they are extensively relieved by hydrodynamic centering of the pumping screw and pumping sleeve
  • Small overall size

Notes

For media with higher viscosities than water it may be necessary to use an electric soft-start device.

For screw pumps with a rotational speed of 3,000 min-1 always an electric soft-start device is necessary.
