Hydraulic Power Units Specifications

Help with Hydraulic Power Units specifications:

Performance Specifications

	Operating Pressure:		The pressure the power unit can deliver at the outlet. The power unit may be expressed as a single pressure rating, or it can be rated to operate over a range of pressure.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Flow:		The fluid flow through the power unit.  This may be a single rating, or have low and high rating points.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Total Power:		The total amount of power the motor / pump can draw or is rated to operate.  Some power units have multiple power sources, and this specification is the power available from all sources.  Power is measured in horsepower, or similar units.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Reservoir Capacity:		The capacity of the power unit reservoir, measured in gallons or similar units.  Some units may have interchangeable or modular reservoirs with a range of capacities.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Physical Characteristics

	Pump Type:		All hydraulic power units have some type of integrated pump.  Some units are available with multi-stage pumps, which perform like multiple pumps connected in series.
	Your choices are...
	Single Stage		Integrated pump has a single stage of operation.
	Double Stage		Integrated pump has two stages of operation.
	Three or More Pump Stages		Integrated pump has three or more stages of operation.
	Multiple Pump Unit		The power unit incorporates more than one pump to pressurize fluid.  A multiple pump unit differs from a multiple stage pump, as a multiple pump unit contains two or more fully separate and independent pumping devices.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Power Source:
	Your choices are...
	Electric Motor		Integrated pump is powered by an electric motor.  Pumps can be powered by single or three phase AC power, as well as DC power.
	Diesel Engine		Integrated pump is powered by a diesel engine.
	Gasoline Engine		Integrated pump is powered by a gasoline engine.
	Pneumatic Compressor		Integrated pump is powered by a pneumatic compressor.
	Other		Integrated pump is powered by a source other than those listed above.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Cooling Method:
	Your choices are...
	None		Unit contains no integrated device for cooling working fluid.
	Heat Exchanger		Device uses a heat exchanger to reduce working fluid temperature.
	Fan-driven Oil Cooler		Device uses a fan-drive oil cooler to reduce temperature of working fluid.
	Other		Device uses a cooling method other than those listed above.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Unit Weight:		The weight of the hydraulic power unit.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Features

	Your choices are...
	Overpressure Protection		Unit is equipped with safety valves that prevent overpressurization of working fluid.
	Baffled Reservoir		HPU reservoir uses baffles to direct fluid flow.
	Fluid Temperature Gauge		Unit is equipped with a temperature gauge, which measures internal fluid temperatures.
	Fluid Sight Level		Unit contains a sight level gauge, which indicates the level of fluid in the reservoir.
	Conforms to NEMA Standards		Conforms to National Electrical Manufacturers Association (NEMA) standards.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
