• pumping industrial and drinking water with temperatures up to 100 ° С;
• increasing and maintaining constant pressure in water supply systems, irrigation, land reclamation.

It is possible to buy pumps TsN400-105 for systems with a working fluid with parameters similar to water. In this case, the level of mechanical impurities should not exceed 0.05% by volume and 0.2 mm in size.

Design features of pumps TsN400-105

The pump unit TsN400-105 includes:

• electric motor;
• pump;
• welded frame or base plate;
• coupling.

A horizontal centrifugal unit with two stages and a semi-spiral inlet is used as a pump. One-way impellers are made in different directions of rotation: right and left. The discharge and suction branch pipes are made in a single housing with a direction in different directions from the pump axis.
When buying a pump TsN400-105, you should know that it includes the following materials:
