End Suction Pump CAD Block

This download holds two end suction centrifugal pumps to EN 733, each with a bearing bracket, a coupling guard and an IEC foot motor on a common steel baseplate: a 32-160 pump with a 2.2 kW motor, frame 90L, and a 65-160 pump with an 11 kW motor, frame 160M. Both motors are 2-pole. Each set comes as a plan block and an elevation block in millimetres at full size, in a DWG for AutoCAD 2010 and later and in a DXF.

End suction pump DWG dimensions

The measurements come from the foundation plan of a typical catalogue pump set, so check them against the drawing of the set you order.

• 32-160: baseplate 900 x 390 x 50 mm, shaft 132 mm above the baseplate, discharge face 160 mm above the shaft, 764 mm from the suction face to the motor end. DN50 suction, DN32 discharge.
• 65-160: baseplate 1120 x 490 x 50 mm, shaft 160 mm above the baseplate, discharge face 200 mm above the shaft, 1112 mm from the suction face to the motor end. DN80 suction, DN65 discharge.

The motor shaft heights follow IEC 60072-1, where the frame number is the shaft height: 90 and 160 mm. The small motor sits on a 42 mm riser so that its shaft lines up with the pump. Motor diameter, terminal box, volute, bearing bracket and coupling guard are representative IEC proportions.

End suction pump drawing in plan and elevation

The suction branch is axial, on the front of the pump, and the discharge points up. On the 65-160 set the fan cowl overhangs the baseplate by 82 mm, so that block is 1202 mm long. The blocks are 900 x 390 x 342 mm and 1202 x 490 x 445 mm. Hidden parts are on layer A-HIDN.

Using the end suction pump block in a pump room

Place the baseplate on its plinth and keep a straight run of pipe before the suction branch. Leave access around the coupling guard and at the motor end for alignment and maintenance. For a pump that sits in the pipe run, compare with the inline pump block. On a P&ID use the centrifugal pump symbol.
