Product Description

Stainless Large Flow Diaphragm Pump


Stainless steel electric diaphragm pump is a new type of pump, in recent years, due to the breakthrough in the diaphragm material, come to be used in petrochemical, ceramics, metallurgy and other industries, characterized by no irrigation and diversion of water, self-priming ability. The motor drives the diaphragm above the plunger at the left and right ends to reciprocate one after the other through the gearbox. In the left and right two pump chambers, equipped with upper and lower four one-way ball valve diaphragm movement, resulting in a change in the volume of the working chamber, forcing the four one-way ball valves alternately open and close, so that the liquid is constantly inhaled and discharged.


Diaphragm Pump Advantages:
- Superior air motor, no leakage and keep strong driving force even use after long time;
- Double thicken fluid cover than ordinary pump
- Perfect sealing design
- PP material, diaphragms and all sealing parts imported from USA
- Easy maintenance
- Lube free
-Same as Graco (Husky)design, spare parts mutually exchange with Graco & Verder.

Diaphragm Pump Application area:
Chemical Industry; Coating Industry; Painting Industry; Dye Industry; Pigment and Textile Chemical Industry; Food Industry; Water treatment Industry; Petroleum Industry; Environmental protection Industry; Pharmaceutical Industry

Industrial Diaphragm Pump Technical Features

  1. Diaphragm structure: The pneumatic diaphragm pump adopts a diaphragm structure, which divides the pump chamber into two parts. Compressed air, controlled by a pneumatic valve, drives one diaphragm forward while the other moves backward, creating a negative pressure in the pump chamber, sucking in liquid and then expelling it through the advancing diaphragm.
  2. Self-priming ability: The pneumatic diaphragm pump has self-priming ability and can start automatically when no liquid enters the pump chamber.
  3. Dry-running capability: Air-operated diaphragm pumps can run without liquid without causing damage to the pump.
  4. Ability to handle fluids with high solids: Pneumatic diaphragm pumps are capable of handling fluids with high solids, such as sewage treatment, waste water treatment, chemical delivery, etc.
  5. Easy maintenance: The pneumatic diaphragm pump has a simple structure, long service life, and easy maintenance and maintenance.
  6. Energy-saving and efficient: Air-operated diaphragm pumps use compressed air as a power source, which consumes less energy and is more efficient than other types of pumps.
  7. Safe and reliable: Pneumatic diaphragm pump does not require electrical equipment, and will not produce sparks, explosions and other dangers when used, so it is safe and reliable in flammable and explosive occasions.
  8. Low cost: Pneumatic diaphragm pump does not require special electrical equipment and control system, the cost is relatively low, and it is suitable for various fluid delivery occasions.
