GENERAL PUMP 1. INTRODUCTION A member of the Interpump Group VS high pressure water plunger pumps have been designed for long life industrial duties and provided they are correctly installed and maintained will give long trouble-free operation. Read and understand this manual before using your pump; it contains the necessary information for the correct installation, use and maintenance as well as some practical suggestion for trouble shooting.
GENERAL PUMP A member of the Interpump Group 3.3 Safety of operation The access into the area when a high pressure unit is working should be strictly prohibited to unauthorized personnel. The area should be suitably enclosed and its perimeter, so far as is reasonably practical, cordoned off and proper warning notices displayed in prominent positions.
GENERAL PUMP 4. PUMP IDENTIFICATION VS SERIES A member of the Interpump Group Each pump is fitted with a rating plate (see Fig. 1) containing the following information: 2. 3. 4. 5. 6. 7. 8. pump model and version serial number max RPM max operating pressure (bar) oil capacity (ltr) and oil specification gear box ratio max flow rate (l/min) Pump model, pump version and serial number should be specified when ordering spare parts. Should the pump be modified (i.
GENERAL PUMP A member of the Interpump Group 7. GENERAL INFORMATION ABOUT PUMP USE VS SERIES 8. CONNECTIONS AND PLUGS The VS pump has been designed to pump fresh filtered water at room temperature. 7.1 Water temperature The max water temperature is 30oC (86oF) 7.2 Max flow and pressure ratings The performance data indicated in the catalog and on the rating plate refer to the maximum performance of the pump.
GENERAL PUMP 9. PUMP INSTALLATION A member of the Interpump Group 9.1 Positioning The pump should be installed flat on a rigid base by means of the four Ø .6” feet. The base should be rigid enough to avoid any misalignment or flexing of the pump/transmission coupling axis due to the torque involved during operation. 9.2 Direction of rotation Fig. 5 shows the correct direction of rotation looking at the pump from the fluid end side.
GENERAL PUMP A member of the Interpump Group 9.5 Filtration VS pumps require 10 to 20 microns water filtration degree. For a correct filtration system three individual filter units should be provided and positioned as shown in Fig. 6. The filters should be installed as close as possible to the pump, allow easy inspection and have the following specifications: a. Capacity of each filter should be at least three times the rated pump flow rate. b.
GENERAL PUMP VS SERIES A member of the Interpump Group 10.3 Water cooling system During operation the cooling water is drained out of the pump though the port (4, Fig. 7) located underneath the pump head. The cooling water line should be connected to the inlet line BEFORE the feed pump as shown below. 11. MAINTENANCE INSTRUCTIONS 11.1 Crank mechanism maintenance. Check oil level on a weekly basis by means of the two oil dipsticks (1, Fig. 8) provided with notches for min. and max. level.
GENERAL PUMP A member of the Interpump Group 11.2 Fluid end maintenance The fluid end does not require periodical maintenance. Service operations are limited to valve inspection and/or replacement, when necessary. VS SERIES Remove the pump head (1, Fig. 12). In order to have access to the delivery valves loosen the 12 valve cover screws (1, Fig. 9) and remove the covers. Once removed take out the delivery valve guide with the spring and valve poppet.
GENERAL PUMP A member of the Interpump Group Reassemble valves and head back in place by following the disassembling steps in the opposite sequence and use a torque wrench at the following settings for valve cover screws and head screws: -Valve cover screw: 144.6 ft. lbs. -Head screws: 339.9 ft.lbs. NOTE: In order to facilitate reassembling operation use our tool p/n F200030140 (1, Fig.
GENERAL PUMP A member of the Interpump Group Once head and collector are removed the cylinders are free to be taken out of the crankcase. Tapping the cylinders all around with a plastic hammer helps to loosen them from possible scaling or deposit accumulated during operation. When removing the cylinders take their weight into account and pay attention not to hit and damage the plungers. VS SERIES Remove the seeger (1, Fig. 22). Remove the rear seal support 1, the rear seal, 2 and the o-ring, 3. Fig.
GENERAL PUMP A member of the Interpump Group Insert a pin of adequate dimensions and smartly tap until the complete pressure packing set is out (Fig. 25). Replace pressure packing set at every inspection. Reassemble packing support and cylinder, Screws 1, Fig 26 should be tightened with a torque wrench set for 4 lbs. Fit each new component of the pressure packing set in the cylinder making sure of the correct order as shown in Fig. 26 and Fig. 27: 2. Packing bushing 3. Packing ring 4. Back packing 5.
