INSTALLATION INSTRUCTIONS Installation of the Giant Industries, Inc., pump is not a complicated procedure, but there are some basic steps common to all pumps. The following information is to be considered as a general outline for installation. If you have unique requirements, please contact Giant Industries, Inc. or your local distributor for assistance. 1. Set-Up and Installation The pump is to be mounted horizontally onto a solid frame that is also to accommodate the drive motor.
Hydraulic System Set Up Intake Feed Tank Bypass Return 1 2 3 4 2.2 Coarse Filter Booster pump Fine-particle filter Gauge to check input pressure 5 LP1000 High pressure pump 6 High pressure gauge 7 Excess, Safety valve Pressure Accumulator The purpose of the pressure accumulator, if installed, is to damp pulsation from the high-pressure pump and thus avoid vibrations in the discharge line. Gas in the pressure accumulator should be pretensioned to 50-60% of the maximum operating pressure.
. Maintenance and Repair To Check Valves: Discharge Valves: Screw out hexagon screws (59) and remove valve casing (54). Pull seal case (46) out of valve casing (54.) Pull valve body (50) and seal case (46) apart. Using pliers, pull spring guide (55) out of the valve casing. Remove discharge valve plate (57) together with spring (56) from spring guide. (55.) Check sealing surfaces of the valve body (50) and discharge valve plate (57.
To Check Seals and Plungers Unscrew hexagon screw (59) and take off valve casing (54.) Remove the screw-in joints (37B) and take off the elbow pipes (37A). Remove drip-return ring (44) from seal sleeve (36). Then pull seal sleeve (36) out of the crankcase. Take the seal tension spring (41) out of seal sleeve (36).
Important! Check the leakage bores Æ4 of the seal sleeves (36) and seal cases (46) for dirt and clean if necessary. The elbow screw-in joints (37B) and elbow pipes (37A) must also be checked for dirt and cleaned if necessary. Important! The Æ4 leakage bore of the middle seal sleeve must be closed by a rubber plug (36A) to ensure water circulation from seal sleeve 1 to seal sleeve 3. Fit the drip- return unit (32/33/35,) the high-pressure seal unit (38,39,40,) and tension spring (41) into the seal sleeve.
Remove connecting rod (conrod) screws, and push the front of the conrod parts forward as far as possible into the crosshead guide. Important! Conrods are marked for identification. Do not twist conrod halves. When reassembling, conrods are to be fitted back onto the shaft journals in their exact original position. Turning the crankshaft gently, tap it out carefully to one side using a rubber hammer. Important! Do not bend conrod shafts.
