Oscillating Piston Pumps, Principle of Operation

From Clark Solutions
 

 
he piston (5) is moved by the electromagnetic field generated by the single wave diode rectified current flowing through the coil (4). Each current pulse moves the piston against the pressure spring (3). This movement by reducing the volume in the suction chamber, opens the valve (6) set in the piston to let the liquid run into the pressure side. When the current pulse dies the pressure spring pushes back the piston toward the pressure side. The increase of pressure closes the piston valve and the liquid flows through the valve (7) set in the pressure connection (8) and into the pressure pipe. This movement creates a low pressure in the suction chamber which opens the valve (2) set in the suction connection (1). The liquid is sucked into the pump and the cycle starts again, 60 times per second (at 60 Hz).
Products & Services
Peristaltic pumps use rotating rollers pressed against special flexible tubing to create a pressurized flow. Search by Specification | Learn more about Peristaltic Pumps
Double diaphragm pumps are positive displacement pumps that compress fluid by decreasing the volume of a chamber containing the fluid. Search by Specification | Learn more about Double Diaphragm Pumps
Rotary vane vacuum pumps and systems move media through the pump using a rotating assembly in the pumping chamber. Typically, there are two or more rotating vanes that move the media from inlet to outlet. Rotary vane vacuum pumps are positive displacement pumps.

Industrial liquid handling pumps are classified in many different ways, and are distinguished by the media pumped and the fluid motive mechanism (dynamic or displacement). Search by Specification | Learn more about Industrial Liquid Handling Pumps
Gear pumps use intermeshing gears to pump various types of liquids. Typically, one gear is the driver and the other is free wheeling. The gears have very tight tolerances so that the fluid being pumped cannot pass through them. Common uses for gear pumps include high pressure, metering, and flow control applications.
