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.
