SAP Series Single Stage Double Suction Centrifugal Pump
CONSTRUCTION DESCRIPTION:
The inlet and outlet of the pump are both under centerline of the pump shaft, they vertical to the shaft centerline and in horizontal direction, You needn’ t dismount the outlet and pipes for inspection, Looking from the driven direction the S type rotary direction is clockwise (or can change to clock wise as user’s requirment)
Main parts of the pump;
(1)Lower Gasing (2)Upper Casing (3)Impeller (4)Shaft (5)Double Suction Seal Ring (6)Shaft Sleeve……..etc
They are made of cast iron except the shaft material being made of fine steel (or Impeller bronze. Shaft s. s).
The impeller working house is composed of pump casing and pump cover , The threaded holes for installing the vacuum gauge and manometer are separately located at the suction flange and the discharge flange . At the bottom of the inlet or outlet flange a drain threaded hole equipped here.
The impeller checked by statical balancing is fixed on the shaft by the shafl sleeves and the shaft sleeve nuts, which axial position can be adjusted by the sleeve nuts, And for the axial force of the impeller, it can be by using adjusted the symmetrical distribution of the impeller and the balanoe the two-sides water.
The pump shaft is supported by two single radial ball bearing.
The bearing fitted on the ecds of the pump casing is installed in the bearing boby and is I ibricated by oil grease.
The double suction seal ring is used to reduce the leakage water from the pressure water house which would flow back to the suction water house.
The pump is driven by the motor through the flexible coupling (It also can be driven by dicsel engine if it is necessary)
The shaft seal is packing or mechanical seals, the packing ring is installed among the packing in order to prevent air from coming into the pump and cooling lubricating sealing case, and while the pump working , it is allowed to let a little high pressure going through the trapezioel groove on the horizontally split face of the pump cover sealing pipe and flow into packing or mechanical seals case, function as water sral
