AP51<br />
Impeller<br />
The impeller is a closed single-channel cast iron impeller<br />
with a clearance of 50 mm. Cast iron is chosen as it is<br />
resistant towards mechanically wearing particles.<br />
The pumps are used for pumping wastewater, sludgecontaining<br />
water, considerable quantities of surface<br />
water and ground water in places such as<br />
• holiday homes,<br />
• public buildings,<br />
• factories,<br />
• garages,<br />
• underground car parks and<br />
• car wash areas.<br />
If permitted by local laws or regulations, the AP51 pumps<br />
can be used for the pumping of sewage from single and<br />
multi-family houses.<br />
Pump and stator housing<br />
The pump housing and the stator housing are made of<br />
cast iron.<br />
The stator housing is dry, i.e. not oil-filled.<br />
Discharge<br />
All AP51 pumps have a horizontal R 2½ discharge port for<br />
threaded connection.<br />
Shaft and bearings<br />
The shaft is made of stainless steel and rotates in maintenance-free<br />
prelubricated ball bearings.<br />
The lower bearing of AP51.65.17 and AP51.65.22 is a<br />
double-row ball bearing.<br />

Materials<br />
Combination of mechanica<br />
bellows seal and lip seal.<br />
The primary shaft seal has silicon<br />
carbide/silicon carbide seal faces.<br />
The secondary shaft seal is a lip<br />
seal. The chamber between the<br />
shaft seals is filled with 0.01 litre of<br />
oil.<br />
Two mechanical bellows seals,<br />
with silicon carbide/silicon carbide<br />
seal faces. The chamber between<br />
the primary and the secondary<br />
shaft seals is filled with 1.2 litre of<br />
oil.<br />
