Mortar Pump

 

a machine for transporting freshly prepared mortar for plastering and masonry work through pipes or hoses to various points at a work site; the mechanism is based on the suction and pressurization of the mortar. A distinction is made between pumps with diaphragms and those without diaphragms, depending on the action of the plunger. In the USSR, mortar pumps have outputs of 1 to 6 m3/hr. Such pumps permit transport of the mixtures up to a distance of 200 m and a height of 40 m. The maximum working pressure created by the pump is from 1.0 to 1.5 meganewtons/m3 (10 to 15 kilograms-force/cm3).
