Product Description
Pumps must have a mechanism which operates them, and consume energy to perform mechanical work by moving the fluid. The activating mechanism is often reciprocating or rotary. A pump is a device used to move fluids (liquids or gases) or slurries by mechanical action. Eco Water Projects offers a variety of pumps of different makes as demanded by Client or requirement.
CLASSIFICATION OF PUMPS
A. Operation Type – Wise Categorizing the pumps as :-
A. CENTRIFUGAL PUMPS: DESCRIPTION AND OPERATION
Pumps add energy to the liquid by either of two methods, centrifugal force or positive displacement. The liquid enters the impeller axially at the smaller diameter, called the impeller eye, and progresses radially between the vanes until it exits at the outside diameter.
B. CENTRIFUGAL PUMPS: DESCRIPTION AND OPERATION
The multiple diffuser design is Primarily used in Multistage pumps since the circular collector is then used to direct the flow to the inlet of the next impeller. This sectional drawing shows a six stage pump where the discharge from each impeller is directed to the eye of the next stage impeller.
C. RECIPROCATING PUMPS: DESCRIPTION AND OPERATION
The second type of pump is a reciprocating pump. Positive displacement pumps impart energy by applying mechanical force directly to the liquid. One design uses a reciprocating piston to force the liquid out of a closed cylinder.
D. RECIPROCATING PUMPS: DESCRIPTION AND OPERATION
Diaphragms can be used in place of pistons to impart the pumping energy. Diaphragm pumps have the advantage of allowing zero leakage around the piston.
E. ROTARY PUMPS: DESCRIPTION AND OPERATION
Positive displacement of liquid can also be accomplished by rotary devices such as a vane type rotary pump. Liquid enters the space between the rotor and stator from the inlet on the right. Vanes in the rotor then apply mechanical force directly to the liquid and force it to move in a confined space as the rotor turns.
F. ROTARY PUMPS: DESCRIPTION AND OPERATION
Intermeshing screws also provide positive pumping action. Screw pumps can also have a single screw or three screws.
B. Utility-wise Categorizing the pumps as:-
