Impeller
The impeller is a closed single-channel cast iron impeller
with a clearance of 70 mm. Cast iron is chosen as it is
resistant towards mechanically wearing particles.
The pumps are used for pumping sewage, wastewater,
considerable quantities of surface water and ground
water in places such as
• public buildings,
• blocks of flats,
• municipal pump pits,
• single-family houses,
• factories,
• garages,
• underground car parks and
• car wash areas.
Approvals
AP70 and AP70.Ex: PA-I no. 4111
AP70.80: PA-I no. 3988
Pump and stator housing
The pump housing and the stator housing are made of
cast iron.
The stator housing is dry, i.e. not oil-filled.
Discharge
All AP70 pumps have a horizontal discharge port with a
DN 80 DIN flange. The flange of AP70.80.09 and
AP70.80.13 is a removable, threaded flange. The port
without flange is threaded R 3.
Shaft and bearings
The shaft is made of stainless steel and rotates in maintenance-free
prelubricated ball bearings.
The lower bearing is a double-row ball bearing.
TM01 7175 4099
The inlet side of the pump housing is fitted with a
