Type A

Qmax=1250m3/h – Hmax=50m 

APPLICATION

The A pumps are universal, general purpose pumps designed to handle different fluids such as clean, cold water, hot water, contaminated water and chemicals. They are applicable in many industries including, for example, water supply, power industry, steel works etc.

DESIGN

Single stage, horizontal, end suction pumps with own bearings, closed impellers and spiral casings. The pumps are of back-pull out design, so they can be disassembled without disconnecting from the pipelines after removing the distant coupling. Mechanical seals of different types can be applied depending on the fluid pumped. The bearings are roller type, oil lubricated.

MATERIALS OF CONSTRUCTION

A pumps are available in different material versions including cast iron, cast steel and stainless cast steel. The materials of construction are selected individually for each application according to the kind of fluid.
