qby QBY Series Stainless Steel Air Operated Pneumatic Double Diaphragm Pump for Chemical Industry Description

Summarize:

QBY series stainless steel diaphragm pumps are suitable for conveying various corrosive liquids, particulate-laden media, high-viscosity fluids, volatile liquids, flammable liquids, and highly toxic liquids, as well as specialized fluids such as ceramic glaze slurries, fruit pulps, adhesives, and temporary tank drainage. This pump is a positive displacement pump that combines the advantages of self-priming pumps, submersible pumps, and slurry pumps. It features stable fluid delivery, strong self-priming capability, low viscosity requirements, minimal vibration, and low noise levels.

Product Details:

The machine's two symmetrical working chambers each contain an elastic diaphragm, with both diaphragms connected via a connecting rod. Compressed air enters the air distributor valve through the pump's inlet port, then flows through the air distribution mechanism into one chamber. This pushes the diaphragm within that chamber to move, simultaneously expelling the gas from the other chamber. Upon reaching the end of the stroke, the reciprocating motion of the diaphragm causes the working chamber volume to change, forcing the two ball valves to alternately open and close. This achieves continuous suction and discharge of the liquid.

Application:

1. Suitable for handling sewage and waste oil in drainage ditches and sewers.

2. This diaphragm pump can transfer naphthenic acid, sodium sulfite solutions, and benzene.

3. Capable of conveying highly toxic, flammable, and volatile liquids, as well as strong acids, strong alkalis, and corrosive liquids.

4. Gas residues and acidic water from the bottom of petroleum refining processes require centralized treatment; our diaphragm pumps can be used to transfer these waste liquids.

Feature:

1. The valve structure of the pneumatic diaphragm pump eliminates the O-ring and piston valve configurations used in traditional valves, adopting a three-way pilot-operated design that removes valve sticking points and prevents pump stalling.

2. The simplified pneumatic directional control valve design avoids costly downtime associated with shutdowns. Fluid components remain intact during valve component replacement.

3. Precise directional signals prevent stalling, enabling faster response times for high-flow delivery, superior performance, minimal pulsation, and stable flow rates.

4. Internal valve sliders are constructed from wear-resistant materials to ensure durability, maintaining unobstructed airflow and flexible directional switching.
