Has been developed for handling corrosive liquids and those containing suspensions of abrasive solids For industrial purposes, they have become obsolete due to their high initial and maintenance costs as compared to centrifugal pumps A diaphragm pump is a pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable non-return check valves to pump a fluid. Reciprocating Pumps Family Tree, Operating Principle and WorkingCharacteristicsApplicationsDifference between Centrifugal and Reciprocating Pump DIAPHRAGM PUMPS. Flow can be smoothed out, but we will discuss this a little later. Like By definition, a reciprocating pump is any machine using reciprocating motion to cause fluid to be moved from one location to another. Diaphragm pumps are reciprocating positive displacement pumps that employ a flexible membrane instead of a piston or plunger to displace the GENERAL INSTRUCTIONS. The manner in which fluid flows through the pump is determined by the design of the pump casing and the impeller Positive displacement pumps, which lift a given volume of the fluid for each cycle of operation, can be divided into two main classes, Reciprocating and Rotary. This can be undesirable in some applications. Reciprocating pumps include piston, plunger, and diaphragm types. Reciprocating pumps of both the plunger and piston type are positive displacement in principle. The most common form of reciprocating Reciprocating Pump: Diagram, Parts, Working & Types [PDF] In this article, we are discussing what is a Reciprocating pump, its parts, types, working principle, uses, and the difference between a reciprocating pump and a centrifugal pump Centrifugal pumps can be classified based on the manner in which fluid flows through the pump. Rotary pumps include gear, lobe, screw, vane, peripheral and progressive cavity pumps The reciprocating pumps are used where relatively small quantity (fixed) of liquid per unit time is to be transferred but at relaively higher pressure. Due to positive displacement characteristics, problems The flow from a reciprocating pump is uneven or pulsating.
