    Water This product has very low water solubility (< 100 ppb). As it has a specific gravity of < 1, if discharged to water, it will initially form a surface film. As the product is non-volatile and has a high binding affinity for particulate matter, it will adsorb to particulates and sediment out.

  • Page 25 Non shearing - delicate media can be pumped effectively with little or no damage. Advantages of Verderflex® Dura pump The Verderflex® Dura pump has many advantages: Physical separation between pump-head and GMU eliminating risk of contamination. Rigid housing design for heat dissipation and accurate hose compression.
  • Page 26 * Pump head weights excluding geared motor unit. Pump construction Refer to Figs 1 and 2. The Verderflex® Dura pump unit is one of the most simple, yet most robust designs of its type, with very few actual moving parts: The pump housing is terminated with a universal one piece port flange.
  • Page 27 11.1 Hoses are available in Natural Rubber, Nitrile Buna rubber, Ethylene Propylene Diene Monomer (EPDM) rubber, Chlorosulfonated Polyethylene (CSM/Hypalon) and Verderprene. This selection is suitable for the majority of applications, but there remain some products which are not compatible with the hose material. 11.2 Hose pumps often appear bulky and large in size when compared to other positive displacement pumps with moderate flow rates.

  • Page 32 HEAVY WEIGHT. When moving heavy weights, lifting equipment should be used to support the weight. HEAVY WEIGHT. Always use lifting equipment safely in accordance with the manufacturer’s recommendations. HEAVY WEIGHT. The pump is provided with a lifting eye, which can be fitted into the threaded hole of the front cover, (located by removing the top left of centre front cover fastening bolt) to assist with lifting.
  • Page 33 1 PUMP CASE INSTALLATION Using a bearing press, press the bearings squarely into the front and rear of the pump body until they locate on the shoulders in the pump housing. The shaft seal should be pressed squarely on top of the inner bearing with the sprung lip facing into the pump cavity.
  • Page 34 Fit the lifting eye to the case. It is also important at this point to attach the filler tube to the back of the pump as it could be difficult to attach once the Geared Motor Unit (GMU) is in place. Line the thread of the breather tube with PTFE tape and tighten into position to give a leak free seal.
  • Page 35 2 DRIVE SHAFT INSTALLATION Apply some triple life bearing grease (Roccol Sapphire 2) to the drive shaft before assembly. Press the drive shaft through the bearing assembly. Once the drive shaft is in place the crescent ring groove should become visible at the rear of the pump.
  • Page 36 3 ROTOR INSTALLATION Secure the rotor to the drive shaft using 4 countersunk socket cap head screws. Failure to use all of the screws could compromise performance of the pump. (See Chapter 4 Table 1 for torque figures) 4 FRONT COVER INSTALLATION The O-ring should sit securely in the groove located around the front of the pump housing.
  • Page 37 Fit the rest of the cap head screws with washers and torque-tighten. (See Chapter 4 Table 1 for torque figures) Fit the inspection window gasket to the front cover. Secure the inspection window to the front cover with cap head screws. Care must be taken not to over tighten the screws, as this may damage the inspection window.
  • Page 38 5 GEARED MOTOR UNIT INSTALLATION Press fit the torque arm bush into the torque arm; then fasten the torque arm to the GMU with the shaft sleeve facing away from the gearbox before attempting to fit it onto the drive shaft. (See Chapter 4 Table 1 for torque figures) Grease the shaft before fitting the...
  • Page 39 Fasten the torque arm to the housing and complete the installation of the GMU. (See Chapter 4 Table 1 for torque figures) Use the crescent clip supplied to stop the GMU from sliding off the end of the shaft. Variations may be secured using bolt and washer.
  • Page 40 6 ELECTRICAL POWER INSTALLATION Remove the cover to the GMU electrical connections. Re-fit the cover, apply power to the GMU. (Danger! This task should be carried out by a qualified electrician) 7 HOSE INSTALLATION Before installing the hose it is best practice remove paint...
  • Page 41 The hose should be inched forward until there is sufficient hose protruding from the suction and discharge ports to fit the tapered flanges (10mm). If the hose passes this point the drive should be reversed and inched back slowly into the correct position. With the hose in position the tapered flanges can be fitted.
  • Page 42 The tapered flange should be pulled toward the housing for as close as is possible ensuring 5mm (16”) of the hose can be seen in the gap between the fixing holes. 8 LUBRICANT he pump must always be filled with the correct amount of lubricant.
