Horsepower (hp) is a unit in the foot-pound-second (fps) or English system. Used to express the rate at which mechanical energy is expended. Horsepower is the work done at the rate of 550 foot-pounds per second and it is equivalent to745.7 watts.

Motor and seals are kept away from the pumped media. The pump has an elongated drive shaft and is submerged in the media. They have no submerged seals, bearings, bushings, or suction check valves. The cantilever or overhung shaft is supported by heavy-duty ball bearings that are located above the pumped liquid.
Pumps that transport or collect and transport condensate collected from a steam system back into the system for reheating and reuse. These pumps close the boiler / steam / condensate loop by returning hot condensate back to the system. This takes advantage of valuable BTUs, which would otherwise go to waste.
Or pumps for removal of unwanted condensate from an HVAC or appliance collection pan.
Designed for clear water applications (agricultural, industrial, and residential). As a general rule, dewatering pumps are limited to a 10% solids concentration and a solids size of 1/4 the diameter of the suction inlet. For applications requiring greater solids handling capability, trash pumps should be used.
Drum pumps are designed to transport or dispense the contents of drums, pails, or tanks. Pumps are driven by a variety of methods including hand operated, electric, pneumatic, and hydraulic driven motors. Explosive environments or flammable fluids may require an intrinsically safe actuation method.
Flexible impeller pumps contain an elastomeric impeller that traps fluid between blades and sweeps it through the pump housing. These low-cost utility pumps are ideal for general transfer.
Pumps that are designed to supply flow to fountains. Fountains are used for esthetic purposes, as well as aeration in residential, commercial, and industrial applications.
A mechanical device that shreds solids and raises sewage to a higher elevation through pressure sewers. A sewage grinder pump will discharge a finely ground slurry into a small diameter pressure pipe. In a low-pressure sewer system (LPSS) the piping downstream of the grinder pump will typically be under low pressure, 60psi or less.
Magnetic drive pumps are operated using a magnetic or electromagnetic drive. They are ideally suited to a variety of applications including laboratory, production line, chemical processing, general transfer utility, as well as OEM applications.
Micro pumps are essential for moving fluids in miniaturized systems. The working principal of a typical micro pump involves interaction of a flexible structure with the working fluid. The flexible structure is deformed using some actuation technique (e.g., piezoelectric or electrostatic actuation) and the deformation provides a positive displacement action for moving the working fluid.
Sanitary pumps are made of materials and constructed in design so that they are readily cleanable. They are widely used in the dairy, food processing, pharmaceutical, cosmetic, and other industries where cleanliness is a concern.
Split case pumps are larger pumps that are used for high flow applications. "Split case" describes the pump housing design. The case around the impeller or pumping mechanism is comprised of two parts that bolt or assemble together. These pumps come in vertical and horizontal configurations.
These pumps are mounted in the tank with the solution. The motor is normally contained in an oil filled cavity that is protected for contact with the liquid by a lip or mechanical seal. They can be designed to pump large solids or grind solids to smaller sizes, transfer wastewater at large flow rates or high pressures, or just pick up water off the floor or the bottom of a tank.
A sump pump is an automatic water pump installed in a contained compartment to remove unwanted water build-up that threatens to encroach on living or equipment space.

Explosion proof pumps are designed to prevent internal or external explosions by enclosing parts that could cause ignition of the transfer media or the surrounding atmosphere. Additionally, they are designed to prevent internal explosions from affecting the surrounding atmosphere and vice versa.
The pump has an integral grinding mechanism in the suction port to grind garbage, sewage, rubber goods, plastic bags, fabrics, etc., to very small pieces and transfer them under pressure.
Compressed fluid goes from initial stage to successive chambers or stages of pressurization; used to generate higher-pressure levels than are possible with single stage pumping.
The pump is specifically designed to meet the strict guidelines established for sanitary process applications. Classifications and ratings may include FDA, USDA, and 3-A.
Priming is the introduction of fluid into the pumping chamber to create the pressure differential to begin pumping at rated service. Self-priming pumps are constructed so that they can create and maintain a sufficient vacuum level to draw fluid into the inlet with no external assistance.
Washdown duty pumps are designed to perform better in wet environments including food processing plants and dairies as well as other high humidity areas.
