Mobile universal pumps MD

Mobile universal pumps MD.

1. Pump installation MD/70 is designed to supply water to fire fighting means, when extinguishing fires on marine and river vessels; on land with the use of slightly contaminated marine and fresh water; and also washing buildings, structures and equipment.

2. Pump installation MD/30 is designed for pumping srednenapryazhennyh fresh and marine waters (from flooded structures, tanks, marshes, ponds, basements, pits); as well as for irrigation and irrigation of agricultural areas.

Pumps equipped with a self-priming device, a set of spare parts for pump kit instrumentation (pressure gauge, the gauge and. etc.); in the quick-release compounds used standard connection head.

Pumps combine the simplicity of the design and schematics, the minimum possible size and weight to provide access for inspection and the replacement of individual components during operation. In the design the pump is provided by a flange connection to the attachment flange engine, bearing housing on the frame through the dampers. The engine and pump located on one frame. The suction cavity of the pump is protected from objects floating in the water. Short stops motoyasu (up to 30 min) does not cause the need for re-filling with water. Pressure the outlet of the pump is provided with a manifold for connection of 2 firefighters sleeveless. Fittings manifolds equipped with removable plugs.

Pumps have marine version "On" class 2 group 2.1 subgroup performance 2.1.3 according to GOST RV 20.39.304-98 and are for year-round operation in climates with moderate and tropical climate (version "U" and "T category I) in accordance with GOST 15150.
