Positive Displacement Polypropylene Diaphragm Pump Chemical Resistant

Positive Displacement Polypropylene Diaphragm Pump Chemical Resistant

Polypropylene Diaphragm Pump Advantages:

1) can work under bad air source, the reversing valve is reliable, not easy broken.
2) smooth air path, no air path obstacle from 1/2'to 3'pump,ensuring a flexible reversing.
3) Reversing valve totally externally maintainable.
4) Less moving parts compared to other diaphragms pumps.
5) pilot type reversing valve with long working life, ensuring the continuous running.
6) one reversing valve suits to different size pumps.

Polypropylene Diaphragm Pump Application:

The Polypropylene Diaphragm Pump can be applied to ship/bus/train unloading, chemical production, batch treatment and mixing, large tank or tank area conveying, common feed-conveying, system flushing, wastewater treatment or fluid filtration, packaging or filling, recycling and recycling. filling, recycling and recycling.

2, Strong acid, strong alkali liquids with corrosion
3, Tanker truck, bilk plant, load and unload of oil products
4, Pickle, fruit pulp, mashed potatoes, chocolates, etc
5, Paint, rubber, pigment and adhesives
6, Various ceramic pulp, grouting, mortar and slurry
7, Various latex, organic solvents, stuffing
8, Stripping of oil carrier (pump dirty water and residual oil)
9, Common hop, thin paste of yeast power, syrup and molasses
10, Special liquid

FLUID SECTION DISASSEMBLY

• Remove the upper and lower manifold (1) and (11).

• Remove the ball (2), “O” ring (3) (47) and ball seat (4).

• Remove the fluid cap (5).

    NOTE: Only diaphragm models use a primary diaphragm(6A) and a backup diaphragm(6). Refer to the aux iliary   view in the Fluid Section illustration.

• Remove the screw (10), washer (9), diaphragm (6A, 6) and diaphragm washer (7, 8).
  NOTE: Do not scratch or mar the surface of (23) diaphragm rod.

FLUID SECTION REASSEMBLY

• Reassemble in reverse order.

• Clean and inspect all parts. Replace worn or damaged parts with new parts as required.

• Lubricate (23) diaphragm rod and 25) “Y” ring with grease.

• Fix the diaphragm rod (23) with the auxiliary installation tool.

• Prior to the final fastening of bolts and nuts, please determine whether the diaphragm (6A,6) is aligned with the fluid cap (5) properly to avoid the twisting of the diaphragm.

• For the models using diaphragm: three rubber diaphragms (6) on the side, which are marked with AIRS SIDE "air chamber" are mounted in face of the pump body.

• Start the pump, check the fastening and sealing after it runs for a period of time.
