Lining process is the Patent technical

The material is virgin, unfilled lining FEP，therefore it has the following features:

(1) Considerably easier and more reliable quality control.

(2) No reduction in the permeation resistance.

(3) Pure pharmaceutical and fine chemical media: no contamination

-Robust pump casing

Pump casing and cover are made of HT200 iron lined with PFA, PTFE, and the impeller is made by WCB and wrapped by PTFA, PTFE, which enables that this type of centrifugal pump could be widely used in corrosive application and wear well. With ductile cast iron armouring absorbs all the hydraulic and pipeworkforces to DIN/ISO5199/Europump 1979. In contrast to partially or non-armoured plastic pumps, no expansion joints are required. Flange with service-minded through holes to DIN;ANSI,BS;JIS. For flushing system and monitoring device as required, the draining nozzle will be offered (pump housing picture)

-Reliable mechanical seal

Shaft seal is outside seal, stationary seal is alumina ceramic ( 99.9%), rotating seal is PTFE filling material or according to customer request.

Closed impeller with flow-optimized vane channels: for high efficiency and low NPSH values. The metal core is protected by a thick-walled seamless plastic lining, the large metal core and increase the mechanical strength considerably even at elevated temperature and high flow rates .Secured screw connection to the shaft to against loosening if the pump is started up in the wrong direction of rotation or in the case of back-flowing media
