Description Performance parameters

Product Overview

MOS type pump is a single-stage double-suction horizontal worm-casing centrifugal pump, which is a new generation of double-suction centrifugal pump developed by our company on the basis of German omega technology, digested, absorbed and optimized. It is the ideal replacement for S and SH series pumps.

Main applications and conditions of use

This series is widely used in urban system water supply and drainage, heating system water supply and drainage, urban water supply; water supply and drainage of iron and steel metallurgical enterprises, petrochemical refineries, chemical plants, thermal power plants and power stations; water supply of fire-fighting systems and air-conditioning systems in factories and mines; agricultural drainage and irrigation and various water conservancy projects.

The conditions of use of the series are as follows:

Working temperature ≤ 105℃

Solid particles ≤ 80mg/L

Allowable working pressure ≤ 25bar

Allowable test pressure ≤ 37.5bar

Structural Features

Compact structure Beautiful shape, good stability, easy to install.

Optimized design of double suction impeller to reduce the axial force to a minimum, and excellent hydraulic performance of the leaf type, and by precision casting, the inner surface of the pump casing and impeller surface and its smooth with significant anti-cavitation performance and high efficiency.

Bearings SKF and NSK bearings are selected to ensure smooth operation, low noise and long service life.

Shaft seal BURGMANN mechanical seal or packing seal is used. It can guarantee 8000 hours of operation without leakage.
