The FPU500 Series peristaltic pumps from Omega offer variable flow capability. A motor turns the pump's rollers, which squeeze fluid through precision bore tubing in a wave-like motion. The fluid does not contact the pump. This makes the pumps ideal for use in sterile, corrosive, or general fluid flow operating environments. The pump is self-priming and non-siphoning. As one section of the tube fatigues, simply move the tube along to an unused section and continue pumping. No tools are required to load the tube. One pump may be used for many different applications, or mount two pumps onto the motor.

Submersible EMU pumps from USFilter David Products are totally sealed, with an entirely self-contained cooling technology that functions equally well when completely submerged or when standing exposed day after day in the baking sun. Cooling is accomplished by an internal heat exchanger that allows the hot oil to dump its heat load to the liquid being pumped. The spiral shaped heat exchanger keeps the oil in contact with the pumped liquid long enough to assure that at least 85% of the heat is exchanged.

Metering pump

Click here to enlarge image

The new PZiA Electronic Metering Pump from Neptune Chemical Pump Co. features an integrated, automatic discharge volume control. Special circuitry is built into the unit to allow for on-board calibration of pump flow under actual process conditions. Once calibrated, the pump can be set to a flow rate, or an analog signal can define the flow rate. The pump will then automatically adjust to maintain the precise flow rate, automatically compensating for changes in temperature, pressure or viscosity. The pump includes a Flow Checker for verification. The Flow Checker is an oval gear meter, which transmits actual flow data to the pump controller. The pump speeds up or slows down as necessary to maintain the required flowrate. The discharge volume during calibration, the instantaneous pump flow rate, or progress during batch operation is displayed on the pump's backlit LCD display, allowing for measurement without the need for stopping pump operation.

The system uses an air compressor to separate air from the water that is moving through the pump, which prevents the pump's venturi from clogging and causing a shutdown. With the air escaping separately, the fluid can continue through the pump without any unwanted blow-by discharge. The separation cycle is continuous. Trash pumps are available in a variety of sizes and models, all with the ability to transfer liquids containing solids up to 3" in diameter.
