Therefore it is a means to change mechanical work into fluid energy. The pump can be widely classified as a centrifugal pump and positive displacement pump. So far, centrifugal pumps are the most widely used pumps.Types of Pumps and their working principles with applications1.1Dynamic Pumps1.1.1Classification of Dynamic Pumps1.1.2Centrifugal Pumps1.1.2.1Radial Flow:1.1.2.2Mixed Flow :1.1.2.3Axial Flow:1.1.2.3.1Axial, Radial and mixed flow pumps impeller dimensions1.1.2.4Axial Split-Case Pumps1.1.3Vertical Pumps1.1.3.1Line-shaft Pumps:1.1.3.2Submersible Pumps1.2Displacement Pumps1.2.1Classification of Displacement Pumps1.2.2Reciprocating pumps:1.2.2.1Plunger / piston type pumps:1.2.2.2Diaphragm pumps :1.2.3Rotary Type Pumps1.2.3.1Rotary Lobe Pumps1.2.3.2Screw Pumps1.2.3.3Progressive Cavity Pumps1.2.4Pneumatic PumpsMaterial used for Pump HousingsDuctile cast iron is one of the most popular casting materials for pump housing. However, they can be made from cast iron or gray iron too. Cast iron houses mainly tend to withstand wear very well and need more rare replacement.Usually, after the manufacturer of casting housing pumps receive CAD images, molds are made from the material needed pump housing thrown into the tolerance needed.Housing Pump - TestingPumps and pump houses undergo a lot of wear because of the nature of these components. Therefore it is important to test these two entities for fatigue, corrosion, and reduction in thickness. There are regular laboratories that carry out the pump housing test. What is Pressed Pump Construction?Pressed pumps are typically made from sheet metal cut to shape and formed to the desired shape. The metal is usually only a few mm thick and can be deformed with relative ease if a blow or knock is delivered to the casing. Pressed pumps are typically designed for simple applications using clean fluids which do not contain solids. Such pumps are usually similar in design by being closed coupled and directly driven by a motor.The construction of pressed pumps is usually used in conjunction with plastics, cast iron and rubber parts for submersible pumps to enable the pump to be more rugged and durable. In end-suction pumps the complete casing is made in stainless steel, however, outlet fittings are usually welded to the casing. This can cause a couple of issues such as the weld can leak due to weld perforation and connections are not usually designed to withstand high pressures. CASTPressedRuggedMetal easy to deform. Usually welded in parts.Longevity through design with wear rings, & long coupledDesigned to be replacedBack pull out designDesigned for clean fluidsAccommodate a wide range of fluidsEfficientParts can be in a variety of different metals and utilize additives for different fluid handling e.g. aluminium bronzeUsually used in conjunction with plastics and gaskets which chemical compatibility also needs checkingThickness means it can accept higher amounts of wear, and is unaffected by small solids passing at high velocityOnly available in 304 or 316 plated and is usually spolt welded during manufacture. The welds are usually the first place to see chemical attack when handling non compatible or aggressive fluids. What is a Cast Pump?Cast pumps are manufactured quite differently and are ruggedly designed. Pumps are manufactured using molten metal formed into shapes via lost foam or sand casting within moulds. The casings are then machined according to designed tolerances. Due to the method of casting, castings are made thick to allow for differences during casting. As castings are thick they ensure many years of trouble-free service. Some models are designed to be long coupled and are able to accommodate a variety of mechanical seal designs ensuring suitability for a wide variety of process fluids thus extending their application across a wide variety of industries. Cast pumps are designed to accommodate wear rings which not only improve pump efficiency but wear in place of the casing. The wear rings are placed either side of the impeller and are then replaced as the pump wears prolonging pump casing life and maintaining efficiency.Cast pumps are robust enough to accommodate large solids passing through as due to the density of the metal the casing will not deform should solids pass through the pump.  Impellers are also dense enough to handle knocks and will not be misshaped.Castings can be manufactured in a variety of different blends to accommodate fluid requirements from stainless steel, to 316L, aluminium bronze or just bronze meaning a pump can be created for your specific fluid requirement or design life.
