Positive displacement pump  is one of the categories of the pump. Positive  displacement pump is also known as reciprocating pump  on the basis of its operation. In general  reciprocating pump a electric motor is used along  with crank and connecting rod assembly to drive the  reciprocating motion of the piston. When the crank  gets rotating motion of from the motor the piston  moves in backward and forward directionSolenoid or  electromagnetic coil can be used as the driving  source. Electromagnetic field created by the solenoid  or electromagnetic coil can control the two and fro  motion of the piston of the pump. Ferromagnetic  materials have a large and positive susceptibility to  an external magnetic field. They exhibit a strong  attraction to magnetic fields and are able to retain  their magnetic properties after the external field  has been removed. By creating this magnetic field  with a certain time interval the reciprocating motion  of the shaft can be obtained.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838373959\"\u003e\u003ch3\u003eCloser Look to a motor-less mini pump\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838373959","offer_id":39469185106013,"sku":"9783838373959","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/495dd581-142c-4895-80be-ace8d9873d90.jpg?v=1769667319","url":"https:\/\/shop.autorenwelt.de\/products\/an-electromagnetic-reciprocating-pump-von-shovon-goutam-und-md-atiqur-rahman","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
