| 1263 6th May, 1941. Rm{William Robotham - Chief Engineer}/MHR.{M. H. Rigby}2/ET. The Correct Depth Gauge Co., C R O Y D O N. Dear Sirs, We are interested in the possibility of using a petrol pump made by you, rated at 80 gallons an hour, with suction heads up to 12 feet and delivery pressure up to 10 lbs/sq.inch. We believe it is called KM.5.A., your drawing No. 5598, and weighs 2 1/2 lbs. If we have got these figures correct, we should like you to send us one immediately for testing. We should also like to know, at the same time, whether you make a smaller pump to give 50 gallons an hour under slightly less severe conditions of suction and delivery heads. An official order will follow. Yours faithfully, | ||
