CONSTRUCTION DETAILS

Machining of impeller made of SOMEDUR

MATERIALS

The hydraulic part is entirely made of thick-walled plastic material. There is no metallic part in contact with the pumped liquid. As a function of the fluids we propose the following materials : SOMEDUR is a material developed by SOMEFLU for special applications with corrosive, charged and abrasive liquids with temperature up to 90° C. On demand other pump types can be realized in SOMEDUR.

CARTRIDGE TYPE MECHANICAL SEAL

A cartridge type mechanical seal developed by SOMEFLU ensures the shaft sealing. This system is independent of the other pump parts and needs no adjustment. Depending on the nature of the fluid the cartridge seal can be executed in the following configurations : q Rinsing out after standstill of the pump for crystallizing or

charged liquids. q Injection of clean liquid during operation for fluids charged

with abrasive matters. If the process allows it is possible to use clear water.

q Filling up with grease of the seal chamber to limit the effects of crystallization if the process does not allow use of water.

q The cartridge can be realized as double-acting seal with external lubrication if the process requires for dangerous or charged fluids.

q Polypropylene PP or PP-EL q Polyethylene PE-HD or PE-EL q PVC q PVDF or PVDF-EL q PTFE q SOMEDUR for abrasive liquids
