Air-operated double diaphragm pumps for metering and transferring of a wide range of fluids. For OEM applications and industrial processes with lower flow rates. The air motor with unbalanced valve requires a lower starting pressure, which allows for more precise flow flow adjustment by regulating the air pressure. The pumps wetted materials are designed for the most aggressive fluids and for use in corrosive environments. The air motor (pneumatic directional control valve and air chamber covers) are made of polypropylene. For use in potentially explosive atmospheres, fully grounding-capable pumps with ATEX certification are available (Ex II2 GD IIB/. IIC 95 degree). Gear ratio: 1:1 Max. free flow rate*: 20 l/min. (5 US gal/min.) Flow rate per stroke (approx.)*: 0.03 liters (0.008 US gal) Flow rate per cycle (2 strokes)*: 0.06 liters (0.016 US gal) Air pressure operating range: 1.5 to 7 bar (22 to 100 psi) Max. Size of solids in suspension: 2 mm (3/32 in.) Max. Dry suction lift*: 6 1/2 ft (2 m) Max. Wet suction lift*: 23 ft (7 m) Weight :2.65 lb (1.2 kg) Suction side connection Inside: 1/4 inch BSP (F) / Outside: 3/4 inch NPT (M) Pressure side connection Inner: 1/4 inch BSP (F) / Outer: 3/4 inch NPT (M) Air connection: 3/8 inch NPSM (F) Wetted materials See table |

Chemical Pumps - Reliable Conveying Solutions for the Chemical and Process Industry |
|
At Kwerk, we offer a variety of chemical pumps in different designs and configurations. Our metering pumps, also known as displacement pumps, enable precise dosing of accurately defined volumetric flows regardless of pressure conditions. They are widely used in dosing technology, especially for the addition of additives. Our plastic centrifugal pumps, also referred to as centrifugal pumps, utilize centrifugal forces to convey liquid media. The rotational speed of the impeller creates centrifugal forces that propel the medium with pressure out of the pump. These pumps are particularly suitable for water treatment applications. The air-operated diaphragm pump conveys media by applying air pressure to a diaphragm, separating the medium from the diaphragm. This provides the advantage of protecting the pump from sludges or contaminants. This pump is ideal for demanding environments. Our drum pumps enable easy emptying of liquids from containers such as drums and tanks. They offer a practical alternative for handling and emptying containers in industrial environments. Eccentric pumps are self-priming displacement pumps that are capable of running dry and are free from cavitation. They are particularly well-suited for frequency control and mobile applications. These pumps are characterized by their robust and reliable construction, ensuring operational safety and low maintenance. Our water jet pumps utilize water as the driving medium to create a vacuum or extract liquids and gases. They find application in laboratory technology for suctioning gases such as oxygen or air and mixing them with water. The submersible pump operates in a vertical configuration similar to a conventional centrifugal pump. Rely on Kwerk as your partner for reliable chemical pumps.
