    VK SERIES GENERAL PUMP A member of the Interpump Group 9. PUMP INSTALLATION 9.1 Installation The pump must be fixed horizontally using the M16x1.5 threaded support feet. Tighten the screws with a torque of 155 Ft.Lb. (210 Nm). The base must be perfectly flat and rigid enough as not to allow bending or misalignment on the pump coupling axis/transmission due to torque transmitted during operation.

  • Page 13: Hydraulic Connections

    VK SERIES GENERAL PUMP A member of the Interpump Group 9.4 Hydraulic Connections To isolate the system from the vibrations produced by the pump, we recommend building the first section of hose adjacent to the pump (for both intake and outlet) with flixible hose. The solidity of the intake section must be enough to prevent deformation caused by the depression produced by the pump.

  • Page 14: Filtration

    VK SERIES GENERAL PUMP A member of the Interpump Group 9.7 Filtration The level of filtration permitted for this series of pumps must be maximum 20 µm (micron). Normally this is obtained by a battery of at least three filters, positioned as shown in fig. 7. The filters must be installed as close as possible to the pump.

    VK SERIES GENERAL PUMP A member of the Interpump Group 9.9 Internal Diameter of the Hose Line To determine the internal diameter of the hose, please refer to the following diagram. Inlet Hose With a flow rate of ~5.3 GPM (20 l/mn) and water speed of 0.5 m/sec. The diagram line that connects the two scales intersects the central scale, indicating the diameters, at a value of ~ 1.1 inch (28 mm).

  • Page 16: V-Belt Transmission

    VK SERIES GENERAL PUMP A member of the Interpump Group 9.10 V-belt Transmissions V-belt transmission is only allowed on versions without a reduction gear. For this pump model, we recommend use of 4 XPB belts (16.5 x 13 serrated). Use an XPC profile only for long durations.

  • Page 17: Transmission Definition

    VK SERIES GENERAL PUMP A member of the Interpump Group 9.11 Transmission Definition To prevent irregular radial loads on the shaft and the relative bearing, follow these directions: a) Use pulleys with v-belts with the size of the groove required/recommended by the manufacturer of belt used. In the absence or directions, follow fig.

  • Page 18: Definition Of Static Pull To Apply On Belts

  • Page 19 VK SERIES GENERAL PUMP A member of the Interpump Group Conclusion: with a dynamometer, loading the belt branch with 75 N as indicated in fig. 14, a “te” bend of aproximately 10.8 mm is obtained. Note : Unless otherwise stated by the supplier of the belts, control of proper pull and its relative re-tensioning should be performed after no less than 30 minutes of motion necessary for the normal asjustment of the belts.
