D Series Between-Bearings Double Flow Axially Split Pumps
Applications: Designed for the supply of water to industrial plants and communities. They are used also for agricultural land irrigation and drainage.
Design: AD series pump units consist of a centrifugal pump, an induction motor, a rubber-bushed flexible coupling with a coupling guard, which are mounted on the foundation. A pump of the make Д 630-90-2-С and its motor drive are mounted on a common base plate.
The pump units shall be rigidly anchored to the foundation, and piping shall be rigidly connected to the pumps.
The pumps are electrically driven horizontal, foot-mounted, single-stage, axially split volute casing centrifugal pumps with a double entry radial impeller. The pump casing is a locating part of the pumps, which incorporates a lower and an upper casing halves bolted together by means of studs.
The pump rotor is carried by antifriction bearings, and in case of the D 6300-80-2-С make pump, by water-cooled plain bearings.
The antifriction bearings are grease lubricated and the plain bearings are oil-ring lubricated ones.
Pump shaft sealing is by means of packed glands.
Sense of rotation of shaft in all the pumps is counterclockwise, if viewed from the drive side.
Upon the Customer’s request, the pumps may be supplied with a rotor for reverse rotation.
