 These Capacity of pumps give in the table are calculated and based on a vertical lift of suction of 1 M and a vertical delivery of 1m with     full stroke at the rate stated.
 A foot valve should be fitted when suction lift is more than 2M.
 In case the liquide is to be forced more than 4M above the pump, vertical check valve on the delivery pipe is desirable.
