For your information...

Marine pumps can be loosely divided into two main types;


1. POSITIVE DISPLACEMENT MARINE PUMPS

Consisting of one or more chambers which are alternately filled and emptied, they are used where viscosity of the fluid is high and their purpose is usually priming and/or to produce high pressure.

1a. Reciprocating Pumps
Reciprocating pumps cause fluid to move using one or more oscillating pistons, membranes (diaphragms) or plungers.

1b. Screw Pumps
Consisting of two or three meshed screws that turn in opposing directions to drive shafts (usually geared) which draw water through the pump system.

1c. Gear Pumps
The most primitive of positive displacement pumps for marine applications, consisting of two meshed gears rotating in a tightly fitted casing.

1d. Piston Pumps
Fluid is pushed by a piston attached to a plunger.

1e. Ram Type Pump
A ram pump uses the momentum of a relatively large amount of moving water to pump a relatively small amount of water uphill. It needs a supply of water situated above it to work.

1f. Vane Pump
Consists of vanes mounted to a rotor that spins inside a cavity.


2. DYNAMIC PRESSURE MARINE PUMPS

Used where there is a moderate to high discharge rate the pressure differential range is low to moderate. Fluid is accelerated by a rotating device (usually an impeller). Dynamic pressure pumps are preferred in systems where low viscosity fluids are used, and are often coupled with a positive displacement pump for priming purposes.

2a. Centrifugal Pumps
Rotadynamic pumps well suited to moving large amounts of liquid through smaller pipes/heads.

2b. Axial Flow Pumps
Fluid enters and exits in the same direction, parallel to a rotating shaft. The fluid is not expedited, rather it is "lifted" by an impeller.

2c. Mixed Flow Pumps
Combine the acceleration and lift of radial and axial flow pumps.
