description Pumping apparatus (10) for pumping concrete, or similar material, comprising at least one pumping unit (11) having both a first pumping cylinder (16) and a second pumping cylinder (17), and also a first pumping piston (21) and a second pumping piston (22) both mobile with a respectively alternating motion inside respective chambers (19, 20) present in the first cylinder (16) and in the second cylinder (17), respectively. The apparatus comprises a motor (31), preferably electric, to drive the first and second piston (21, 22) with an alternating motion by means of suitable movement means (26, 27).
