Abstract
A pump for pumping a pumping mud or a slurry. The pump includes a housing having a pump chamber and an intermediate fluid chamber, a membrane arranged within the housing, a reciprocal pumping member operatively arranged in the intermediate fluid chamber, and an accumulator fluidly connected to the intermediate fluid chamber via a throttle. The pump chamber has a fluid inlet and a fluid outlet. The membrane delimits the pump chamber from the intermediate fluid chamber.

A pump for pumping a pumping mud or a slurry, the pump comprising:
- a housing comprising a pump chamber and an intermediate fluid chamber, the pump chamber comprising a fluid inlet and a fluid outlet;
- a membrane arranged within the housing, the membrane delimiting the pump chamber from the intermediate fluid chamber;
- a reciprocal pumping member operatively arranged in the intermediate fluid chamber;
- and
- an accumulator fluidly connected to the intermediate fluid chamber via a throttle.

A method for dampening pressure fluctuations in a pump, the method comprising:
- operating the pump to pump a pumping mud or a slurry;
- providing at least one accumulator which is fluidly connected to an intermediate fluid chamber of the pump via at least one throttle;
- and
- dampening, via the at least one accumulator, pressure fluctuations in the intermediate fluid chamber which have a frequency which is higher than a reciprocating speed of the pump.
