The operation of the pump, though a bit complex, is an interesting one. As shown in the figure, the circular ring, which accommodates the slippers is concentric with the central valve arrangement . Due to this, the piston doesn't have any relative reciprocating motion inside the cylinder. No oil is pumped or sucked in and although the pump is rotating no fluid is delivered, during this state. But this is only until the arrangement is concentric. As soon as the circular floating ring is pulled to the right the pistons in the cylinder undergo a reciprocating motion.
The lower piston moves inwards and discharges fluid through the lower port. The piston moves till the horizontal position and then moves outwards in the opposite direction, drawing in fluid through the upper ports. Thus in this way the top ports act as suction ports and the lower ports act as discharge ports. If the circular ring is pushed to the left direction, the suction and discharge ports are reversed.
All the variable displacement pumps are positive displacement pumps, with a constantly rotating arrangement and a variable discharge design. If the system has more than one pump, a non reversing locking gear is provided, which prevents the reverse operation that might take place at times when only one pump is operating. Moreover, the arrangement is such that as soon as the pump is stopped the locking gear would come into action .

What is induction pump?
Induction pump is a term used to describe any type of pump that depends on electromagnetic induction for its operation. These pumps are often used for liquid alkaline metals that are expected to reach temperatures between 800 and 1000 degrees Celsius.
What are the names of the principle parts of a centrifugal pump?
The principle parts of a centrifugal pump are the pump casing, also called a volute, and the impeller. The other parts are the pump shaft, bearing(s), shaft seal, the wear rings, and the inlet and outlet. The impeller is mounted on the pump shaft. The pump shaft is coupled to an external power source like a motor. The motor turns the shaft, the shaft makes the impeller turn and the fluid being pumped is put in motion. The volute causes a change in pressure in the fluid. The shaft seal stops the fluid from leaking out of the casing (volute). The wear rings separate the high and low pressure areas inside the casing. The bearing(s) make the shaft turn easier. The inlet and outlet parts of the casing connect to the fluid piping system.
How the correlation between hydraulic motor and hydraulic pump?
Internally, they're pretty much the same. The difference is the operation expected of it - a hydraulic pump converts mechanical energy to fluid energy, whereas a hydraulic motor converts hydraulic energy to mechanical energy.
What is the working principle of double acting pump?
double acting pump. .to a maximum when the piston is approximately halfway through its stroke. The variation in pumping rate can be reduced by using both sides of the piston to pump fluid. Pumps of this type are called double acting. Fluctuations in pumping rate can be further reduced by using more than one cylinder.
