Condensate pumps

The QI series condensate water pump is a single stage, single suction (axial suction) centrifugal pump. The Pump is mainly used for transferring condensate water from the condensate in power station, also can be used for transferring other liquid which is physically and chemically similar to water. This pump has high suction performance. The temperature of the liquid should below 80 degrees centigrade, inlet pressure is not more than 0.6MPa. Material of main parts: medium contacting parts like pump casing, cover, seal ring and shaft sleeve: cart iron; impeller: silicon-brass; shaft: high quality carbon steel.

●QI type condenser pump is designed with performance and dimensions specified to the International Standard ISO 2858. 
●QI condensate pump is divided into the casing and the casing cover from the back face of the impeller i.e. back pull-out design.
●QI condensate pump has the advantages for ease of inspection and maintenance. When inspection, only dismantle the intermediate connector between pump coupling and motor coupling. The rotating element can be completely removed without disturbing the casing, suction and discharge pipeline and motor
●The pump volute form is composed of casing and casing cover. The rotating element consists of impeller, shaft and rolling bearing. The rotating element is carried by the rolling bearings mounted in a hanging bearing bracket and radial and axial thrust is supported by the bearings.
●In order to balance axial thrust, there are both wear rings in front and at the back of the majority of the impeller and the balance hole is on the back shroud of the impeller. The axial thrust of some pumps is not big enough, so there is no wear ring and balance hole at the back of the impeller.
