In a gas pumping system including a first stage rotary lobe pump for pumping gas to a second stage liquid ring pump, cooling liquid is injected into the compression zone of the rotary lobe pump so that the liquid mixes intimately with the gas being compressed in that zone and reduces the temperature rise of the gas in that zone in order to reduce heat transfer from that gas to the lobes of the rotary lobe pump.
