Centrifugal Pump
Centrifugal Pump Centrifugal Pump - The centrifugal pump consists of an impeller blades fixed on a rotating shaft and enclosed in a casing; has a central inlet and a peripheral discharge connection. The rotating impeller creates flow in the liquid by the velocity derived from centrifugal force; the greater the rpm, the higher the head against which the centrifugal pump can deliver; special types for "chopper" and "pulverizing" applications.


Vane Pump
Vane Pump Vane Pump - Vane pumps are positive displacement pumps. Popular usages are with lubricous liquids, for example: engine oil and fluid power oil hydraulics. Flow Generation characteristics are claimed to be superior to gear pumps, but wear characteristics and expense is worse. Vane pumps use two or more spring loaded, or hydraulic loaded, vanes spinning within an eccentric enclosed space to generate flow.


Gear Pump
Gear Pump Gear Pump - External type gear pumps most often designed for generating flow in lubricous liquids, regularly found in fluid power hydraulic circuits. The concept involves generating oil flow by two gears meshing together in a relatively tight enclosure. Size of the gears & tightness of enclosure determine what the pump is capable of generating. "Internal gear" tend to be for lower rpm applications with higher viscosity liquids.


Lobe Pump
Lobe Pump Lobe Pump - Lobe pumps are designed to displace sludges, slurries, and very high viscosity liquids even up to 1 million cente poises. Common applications arise for flow generation in, pulp and paper, chemical, food, beverage, pharmaceutical, and biotechnology industries. Also offer superb sanitary qualities, with high volumetric efficiency, and good clean-in-place and service-in-place (CIP/SIP) characteristics.


Hose / Peristaltic
Hose / Peristaltic Hose / Peristaltic - A positive displacement pump, correctly characterized as "peristaltic" In the hose / tube / peristaltic pump, fluid is contained within a flexible tube. A rotor which has attached to it a number of 'rollers', 'shoes' or 'wipers' is rotated and causes them to compress the flexible tube. As the rotor turns, the part of tube under compression closes, forcing the fluid to be pumped to move through the tube.


Dosing / Metering Pump
Dosing / Metering Pump Dosing / Metering Pump - A precision pump of two general types, both typified by volumetric repeatability, that deliver an exact amount of liquid with each stroke or revolution. Type 1 where volume flow is changed by the speed of rotation. Type 2. where the volume flow is changed by changing the length of a reciprocation stroke. Designed to send shots of liquid at defined intervals and of changeable volumes into another liquid.


Intensifier / Injection Pump
Intensifier / Injection Pump Intensifier / Injection Pump - Actually designed for use in a metering application. General design: A helical groove on the circumference of the plunger is aligned with a port in the cylinder wall. The plunger is rotated to cause the volume of liquid spilled off down the helical groove, to be increased or decreased. The plunger is normally driven by a cam shaft. Use: For feeding the injectors to individual large diesel engine cylinders.


AODD / Diaphragm Pump
AODD / Diaphragm Pump AODD / Diaphragm Pump - Initials from "air operated double diaphragm" normally a shop air line pressure device (150psi). The abbreviation "AOD" is is a registered trademark. This "double diaphragm" should never be confused with "double layer diaphragm" as used in 5000 psi diaphragm head metering pumps. An "AODD" is different form a double layer diaphragm head metering pump.


Plunger / Piston Pump
Plunger / Piston Pump Plunger / Piston Pump - The differentiation between plunger is that plunger slides through a static packing seal, where as a piston has a dynamic sliding seal on its circumference. The drive of the reciprocating piston or plunger motion, most commonly from a crankshaft, also there are swashplate and cam drive elements. The commonest applications are fluid power hydraulic, and high pressure water pumps.
