The factors that govern the factors of speed of reciprocating pump are:-
1. Cleanliness of Working Fluids
2. Temperature of Working Fluids
3. Piping Layout
4. Pump Foundation
5. Design of Suction and Discharge Pulsation Dampeners
6. Regular Maintenance

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
In case of emergency, if the cylinder stops, the motor does not. So it can be harmful for motor. Designers couple the high power motor to the cylinder of pump by means of a clutch. so the motor can continue to rotate while the cylinder stops. Also in case of closing the outlet valve of a pump, the pressure in the cylinder can fail the cylinder or crankshaft and accessories. in this case the clutch can separate the power from motor to the pump and prevent failure of pump.

we can pump water in high current
it runs without fluctuation i.r continuous flow......
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.
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.

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
momentum.
Yes. However in some application we can use a rotary type.
The power required by a reciprocating pump is directly proportional to the discharge it produces. When the discharge increases, the power needed to maintain that flow rate also increases. This relationship is governed by the pump efficiency and the pressure head against which the pump is operating.
i would say the piston
