Dbw Sanitary Electric Diaphragm Pump

DBW food grade hygienic sanitary electric diaphragm pump is widely used in Beverage industry, pharmaceutical industry, dairy industry, food industry, meat industry, cosmetics industry, condiments industry, daily chemical industry, alcohol industry etc.

Advantage:

1 - The flow parts of QBW pneumatic diaphragm pump is made of stainless steel material (SS304, SS316, SS316L) with hygienic/sanitary food grade requirements.

2 - Pump uses precision casting.

The surface is smooth and tidy and has a higher strength.

3 - Valve ball is further processed by a special machine, which has high roundness and good sealing performance.

4 - Accurately calculate the moving distance of the diaphragm to reduce the force of the diaphragm and have a longer service life.

5 - Four bolt connection design, good sealing performance, the actual dry suction can reach 0-4 meters.

6 - Three-section upper and lower cover, flexible installation.

7 - The integrated design of the diaphragm retaining block has excellent pressure resistance and high temperature resistance and is widely used in food, alcohol, daily chemical, beverage industry.

8 - Connecting rod of the diaphragm is made of wear-resistant stainless steel, which has better corrosion resistance and longer life.

Working principle:

The motor (4) drives the diaphragm (2) above the plunger at the left and right ends to reciprocate through the reduction gear box (3).

In the left and right pump Chambers, the movement of the upper and lower four one-way ball valves (1) affect diaphragm the change in the volume of the working chamber, forcing the four one-way ball valves to open and close alternately, thus continuously inhaling and discharging the liquid.

Sanitary electric double diaphragm pump notice:

1 - No valve is allowed to be installed at the pump outlet, if it is necessary, please install safety valves in the outlet, working pressure cannot exceed 0.4MPA.

2, The lubricant oil should be added timely to keep the normal operation of the lubrication system.

3 - The ambient temperature of the pump in use shall be less than 40℃, and the motor temperature shall not exceed 75℃.

4 - The medium to be transported and its temperature shall be within the allowable range of the pump material.

5 - When the pumped liquid is easy to precipitate for the crystallization of the medium, the pump should be cleaned after finishing operation so as to avoid damage when open again.
