Pumps

SPU Circulation pump SPU Circulation pump The SPU circulating pump (shown: SPU5000) is used for circulating buffer/barrier fluid in seal supply systems (to increase the cooling capacity). The SPU is suitable for water and other liquids of similarly low viscosity. The SPU is available in 5 basic versions:
SPU1010: without explosion protection
SPU2040: with mechanical seal, with magnetic coupling as an option, ATEX conform
SPU2063: with mechanical seal, with magnetic coupling as an option, ATEX conform
SPU4040: with magnetic coupling, ATEX conform
SPU5000: sealless pump, ATEX conform
HPS Screw pump HPS Screw pump 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
