Type B

Qmax=5000m3/h – Hmax=90m

APPLICATION

The B pumps are designed to handle hot, clean and slightly contaminated water. They can be applied in water supply systems, industrial cooling systems, and, for the ability to pump hot water, in district heating and power plants.

DESIGN

Stationary, horizontal, double suction, horizontally split pumps. The suction and delivery flanges are arranged horizontally in-line. The upper part of the casing can be lifted and the entire rotating assembly can be taken out for repair without disconnecting the pump from the pipelines. The oil-lubricated roller bearings and the mechanical seals installed on both sides of the shaft are equipped with cooling chambers, so the pumps are able to handle hot fluids.

MATERIALS OF CONSTRUCTION

The casings are made of cast iron or, for higher heads, of cast steel. The impellers are of cast iron or stainless chromium cast steel.
