Applications

Volute casing centrifugal pump, end suction type, main dimensions and performance according to DIN 24255 standars with complementary size to extend performance range. For duties of approx. 4000 m³/hr flanges DN 500/500 are required. Up to a duty of approx 500 m³/hr (pump flanges DN 200/150) the pumps are also available in space-saving block design type "APEbloc".

APE pumps are designed to handle media:

• Which are clean or slightly abrasive
• Having temperatures up to 140°C
• With viscosities not exceeding 150mm2/s (cSt)
• Which can easily be pumped
