Hydraulic pump types include gear, vane, and ___ pumps.

___ is a localized gaseous condition within a stream of fluid that occurs when pressure is reduced to vapor pressure.

A lobe pump requires ___ to drive the lobe-shaped driven gears.

___ is the volume of hydraulic fluid moved during each revolution of the shaft of a pump.

A ___ pump has an inner rotor that meshes with the gear teeth of an outer rotor.

A variable displacement pump varies the amount of hydraulic fluid with movable internal components while the ___ of the prime mover remains fixed.

Bent-axis piston pumps are different from axial piston pumps because their ___ are at an angle (offset).

A(n) ___ plate is an angled plate used to extend and retract the piston in an axial piston pump.

The main categories of hydraulic pumps are dynamic and ____ pumps.

The most common method to vary the angle of a swash plate is through ____.

A ___ is part of a vane pump and houses the canes, rotor, and cam ring, which are all placed between two end plates.

Gear pumps may be external, internal, lobe, or ___.

____ is the highest amount of pressure at which a pump can create fluid flow.

A(n) ____ vane pump allows adjustment of the flow rate of the pump.

Although lobe pumps can be used in pneumatic applications, they are typically used in hydraulic applications to move products such as slurries, pastes, and solids.

Hydraulic fixed-displacement pumps cannot vary the amount of fluid flow that they produce during operation without changing the speed at which they operate.

External gear pumps have two different sized gears.

A balanced vane pump has an elliptical cam ring.

Displacement is the fluid flow that a pump can produce.

Axial piston pumps create a smooth fluid flow for piston pumps.

Changing the angle of the swash plate in a variable-displacement piston pump does not affect the distance of how far back a piston pulls.

Gear pumps operate through the extension and retraction of multiple pistons.

All bent axis piston pumps are variable.

Dynamic pumps include gear, vane, and piston pumps.

Pseudocavitation can be caused by low reservoir fluid.

Gear pumps have the highest level of loudness while in operation.

Hydraulic pump schematic symbols provide direct information on pump type.

Vane pumps are typically used in applications that require movement of high viscosity fluids.

A radial piston pump consists of pistons located parallel to the pump shaft

Radial piston pumps can be classified as cam or rotating piston pumps.

All hydraulic pumps have nameplates fixed to them.

The length of a piston is the main determinant to the amount of gpm that an axial piston pump can produce.

Gear pumps are ideal for equipment operators in dirty environments.

A bent-axis piston pump can operate at pressures above 10,000 psi.

The rotor of a variable displacement, pressure compensated, vane pump is centered with a crescent seal.

All gear pumps are fixed displacement pumps.

Unbalanced vane pumps have the simplest design of the various types of vane pumps.

Gerotor pumps are used for high-pressure applications of greater than 1000 psi.

Positive displacement pumps are typically classified as fixed or variable.
