Type SPN 200
Pump types SPN 200 + SPN 200 RH can be supplied for either water or electric heating. All other sizes are available only for hot water heating.
Type SPN 500
All SPN pumps are equipped with newly developed mechanical lip seals for up to 8 bar backpressure.
Type SPN 500 RH, variable
All pumps are driven by powerful geared motors via flexible couplings.
Type SPN 750/SPN 1000/SPN 1500/SPN 2000/SPN 3000
All pumps have specially designed pump gear teeth. Their output is very stable even at high back pressures.
Type SPN 1500 RH, Type SPN 3000 RH, variable
After removing the front pump cover, the inside of the pump is easily accessible.
Type SPN 4000/SPN 5000/SPN 6000/SPN 8000
All pumps have duplex bearings on one hand of the shafts only. The advantage of this is that only one maintenance-free mechanical seal is needed per shaft.
Type SPN 8000 RH, variable
The direction of flow of all pumps can be changed, i.e. they can run forward or in reverse.
