Structural Characteristics

Pump is vertical structure,motor cover and pump cover are connected to be designed.Beautiful appearance,little occupied area.It can be used outdoor if a protective cover is installed.

Inlet and outlet diameter of pump are the same and they are on the same center line,which can be installed on the pipeline directly just like valves,and the installation is very convenient.

Excellent foot design makes the installation and steadiness of pump convenient.

Pump shaft is lengthened shaft,and this solves the vibration problem caused by coupling drive that is applied by common centrifugal pump shaft and motor shaft.Chromeplate treatment shall be proceeded on surface of pump shaft,which greatly prolongs the service life of pump.

Impeller is directly installed on the motor lengthened shaft.There i no noise when pump is operating,motor shaft applies low noise bearing,which greatly improved the operating environment.What’s more,non-malfunction working time of pump has prolonged 3 times than the common pump.

Mechanical seal is used on the shaft seal,which solves the severe leakage problem caused by packing seal of common centrifugal pump.Static ring and rotating ring of sealing are made of silicon carbide,which prolongs service life of seal.

There is a exhaust hole on the pump cover.Outlet hole and pressure hole are on the flanges downside and two sides of pump casing in order to make pump operate,maintain normally.

Unique structure,so there is no need to dismantle pipe system.Just dismantle pump cover nut,then begin to maintain.It is very convenient.

Series connection,parallel connection and enlarging of pipe diameter can be applied according to requirements,namely,capacity and head.

Max working pressure of pump system≤1.6MPa,namely “pump suction pressure+pump head ≤1.6MPa”.When ordering,system working pressure shall be marked.If pump system working pressure is more than 1.6MPa,it must be specified when ordering so that cast steel material can be applied when manufacturing.

Environmental temperature＜40℃,relative humidity＜95%.

Volume content of solid particles in the transported medium shall no exceed 0.1% of unit volume,granularity＜0.2mm.

Remarks:If medium contains tiny particles,please specify when ordering,so that the wear-resistant mechanical seal can be applied.
