Product Detailed
we supporting custome : Ingersoll Rand company. inlet manifold discharge manifold - For Diaphragm pumps - For OEM

What are Diaphragm Pumps?


       These are pumps without any electrical motor and run with an air pressure ranging from 1.3 to 8.0 bar. They are simple to run with minimum maintainance cost and down time. All type of liquids can be pumped. Only the MOC and capacity of pumps will vary depending on application and buyer requirements. Sizes vary from 1/4" to 3" and they are available in PP, PVDF, SS & Aluminium Models.


Product Range

Quande produces a variety of casting products, including stainless steel, carbon steel, duplex ,aluminium alloy and specialized nickel alloy that are conformed to international standard such as ASTM, BS, DIN and JIS.

The current major product mix comprises, including stainless steel, carbon steel, duplex and nickel-based alloy. Major applications of the casting include, but are not limited to, the following:

Valve and pump components, Pipe fittingPrecision components for marine, oil, gas, chemical, textile and food processingStructural brackets for architectural curtain and walling and cladding systemsAccess covers and drainage gratingsMedical applications


1.Ceramic material for main valve and reversing valve ensures longer life, more stability and working in dirty compressed air ( most occasions, air filter become option).

2.Without ice with the muffler. Innovative design with the exhaust space of the pump, some of muffler inside, this makes the air outlet smooth.)

3.Outward parts of the pump are all die casted aluminum and special environment-protected painting, makes the pump with elegant appearance.

4.Large flow capacity. Innovative design of chamber maximizes the flow capacity. Seamless adjustment with inlet valve, or even close the valve, without damaging the pump.

5.Low consumption compressed air. Innovative design of the air flow system, minimizes the usage of compressed air to achieve maximum performance.

6.Light and small size, movable.

7.Modularization of main valve and air motor. No broken, easy to disassemble and repair.

8.Optimized design greatly reduces overall component number of pump. Significantly improve performance, help for maintenance.

9.For power variety, pneumatic pump’s flow capacity normally lowers than electric pump, but BSK pump is workable in series at certain conditions. This can largely satisfy customer request.

10.Innovated design of sealing structure and material, totally solve the leakage inside or outside.

11.Our pump can be started with low air press ( only 1.5 KG air press can start my pump).
