Motor Driven Diaphragm Pump Stainless Steel For Swimming Pool Water Treatment

Double diaphragm metering pump , Lubricating oil not to pollution system after diaphragm rupture

Description:

1. Driving end

A. Eccentric mechanism driving, compact structure, small installing space.
B. Unique worm wheel structure or screw structure, promises the stable and successive work of the mechanic driving parts.
C. The roller bearing in the bottom of the screw promises the long time stable heavy-load running.
D. Oil bath lubrication systerm, long service life.
E. The flow is adjustable when running or stopping. The adjustment can be hand, electricity, air driving or frequency conversion.

2. Hydraulic end

A. Hydarulic driving diaphragm promises the long service life of the diaphragm.
B. High precision one-way check valve structure make dosing pumps precisely add.
C. Inner adjustable pressure relief valve can automatically protect the diaphragm and pump head from being damaged.
D. PVC, PVDF, 316SS, alloy 20 or 22, Hastelloy and other materials of pump heads are suitable for various fluids.
E. Optional pressure type double-diaphragm leaking hunting alarm ( on site or long range )

Features

1. No leakage, maintained conveniently, low noise, durable in use.
2. Measuring precision is better than mechanical diaphragm pump,sealing property is better than piston pump.
3. Matching a stroke adjuster to realize remote automatic controlling.
4. The diaghragm is made from multilayer complex structure to promote the life span, the first layer is Teflon anti-acid diaphragm, the second is EPDM stretch rubber, the third is 3.00 mm thick SUS304 that supporting the iron corn. The fourth is also the EPDM stretch rubber to cover all of the body.
