![]() ![]() In power applications where continuous duty plunger pumps are needed, solid ceramic plungers may be used when in contact with water and oil, but may not be compatible for use with highly acidic media types. The plunger, discharge valves, and suction valves come in contact with the transferred medium, and material choices are based on the fluid transferred. ![]() For example, plunger pumps that function in general service or oil service applications often have an iron cylinder and plunger. Component materials include bronze, brass, steel, stainless steel, iron, nickel alloy, or other material. Plunger pumps' component materials are chosen for wear and contact with the type of medium. A stuffing box may be composed of bushings, packing or seal rings, and a gland. Create a new ODBC Data Source (preferably a 64-bit) following the steps below. A stuffing box or packing is used to seal the joint between the vessel where the medium is transferred and the plunger or piston. Seals are an integral part of piston pumps and plunger pumps to separate the power fluid from the medium that is being pumped. The power needed from the drive is proportional to the pressure and capacity of the pump. The overall capacity of the piston pumps and plunger pumps can be calculated with the area of the piston or plunger, the stroke length, the number of pistons or plungers and the speed of the drive. The volume of the fluid discharged is equal to the area of the plunger or piston, multiplied by its stroke length. Piston pumps are used in lower pressure applications. Plunger pumps are used in applications that could range from 70 to 2,070 bar (1,000 to 30,000 psi). The pressure in the chamber actuates the valves at both the suction and discharge points. Rotary piston and plunger pumps use a crank mechanism to create a reciprocating motion along an axis, which then builds pressure in a cylinder or working barrel to force gas or fluid through the pump. The plunger or piston is actuated by a steam powered, pneumatic, hydraulic, or electric drive. Contact us for technical advice or sales on +44 (0)1209 314700 or email:. The former can exist in the absense of the later. Pascals Principle tells us that a pressure (F2) will be applied on the much larger. Ram pressure is the force per unit area due to a body moving through a medium. Piston pumps and plunger pumps are reciprocating pumps that use a plunger or piston to move media through a cylindrical chamber. A guide to gasket pressure, and how to seal in high and low pressure applications. A force is applied to a piston (A1) that presses on an enclosed fluid. The invention of the plunger pump is attributed to Samuel Morland based on a patent of 1675. ![]()
