Bellows Metering Pumps
Bellows metering pumps operate on a positive displacement principle. The rotation of the motor shaft is transmitted into an up and down motion through a lever pivot crank mechanism. This motion provides a continuous squeezing and relaxing force on a bellows module, forcing fluid in and out of the module.
Pumps are designed to displace both corrosive and noncorrosive fluids.
Typical applications include film and x-ray processors, silver recovery systems, wafer and silicon chip washers and silicon chip washers and processors, detergent dispensers, blood analyzing equipment, industrial floor scrubbers, thermo therapy equipment, waste removal systems, and wastewater and water treatment systems.

Centrifugal Pumps
Centrifugal pumps are designed to transfer both corrosive and non-corrosive fluids at maximum hydraulic efficiencies. Centrifugal pumps are not self-priming and must be used in applications where flooded suction exists.
These pumps can not run dry. Typical OEM applications include commercial and residential heating and cooling systems, commercial coffee urns, ice makers, dish and glassware washers, laundry appliances, plating systems, agricultural sprayers and industrial floor scrubbers.

Magnetic Drive Pumps
Operation is similar to the standard centrifugal pumps, except the impeller is driven with a magnetic coupling, eliminating the need for a shaft seal. Magnetic drive pumps must be used where flooded suction exists. Typical OEM applications include film processors, laser and x-ray cooling systems, medical, scientific and laboratory equipment
and silver recovery equipment.

Oscillating Pumps
Oscillating pumps are self-priming, corrosion resistant, have no dynamic seals and are constructed from FDA accepted materials. An elastomeric impeller extends through a spring and armature and into an electric coil.
Each pulse draws the armature and impeller forward against the spring, causing the impeller to pump a volume of liquid out through the outlet port. A valve in the impeller prevents backflow of liquid.
Actual flow may vary from pump to pump. These pumps are intended for replenishing, transfer and circulating installations. Typical OEM applications include film and microfilm processors, litho and graphic arts plate processors, detergent dispensing, chemical mixing, medical, scientific and laboratory equipment.
