Priming is not required in a reciprocating pump because these pumps are designed to create suction on their own. Unlike centrifugal pumps, which rely on a fluid-filled casing to initiate flow, reciprocating pumps utilize a piston or diaphragm mechanism that draws fluid into the chamber during the suction stroke. This action effectively removes air and allows the pump to operate efficiently without prior filling. As a result, once the pump is started, it can effectively handle both liquids and gases without the need for priming.
it runs without fluctuation i.r continuous flow......
Priming of any pump is the same - it means filling the pump with liquid to get it to pump because the pump will not fill itself with liquid from being dry (it won't self-prime).
As the reciprocating pump operates though the reciprocation of the follower,it guides the suction and the compression of water in the pipe.That's so when the rotary motion of the rotor blade is converted into the reciprocating motion, which deliver it to the reciprocating pump, the suction and discharge takes place.
When the actual flow (Qa) is greater than theoretical flow (Qt) in a reciprocating pump it is negetive slip.

Reciprocating pumps will deliver fluid at high pressure (High Delivery Head).They are 'Self-priming' - No need to fill the cylinders before starting.
because they deliver a fixed quantity of the discharge irrespective of their rpm
we can pump water in high current
it runs without fluctuation i.r continuous flow......
Some rotary pumps are self-priming when dry. These pumps have a priming chamber that automatically does the self-priming when the pump is not in use. To prime a pump yourself, the priming plug should be removed. Water should then be poured into the pump. The entire priming process should take no longer than five minutes. If it takes longer than that, it could be indicative of a mechanical problem.
A reciprocating pump is an advantageous pump. Centrifugal pumps convert energy into rotation to power themselves. A reciprocating pump uses a back and forth linear motion.

The fuel pump requires no priming.
air vessel are use in reciprocating pump for to damped out the pressure variation during discharg so it is not fiteed on discahrg pipe the high pressure damp the pump
