GRP Series Installation, Operation & Maintenance Manual Project: _________________________ Installation: ___________________ Pump Model: ____________ Serial Number: ___________ PN# GRPIOM REV. 6/12 HOMA Pump Technology, Inc.
GRP Series EQUIPMENT INVENTORY AND This manual is intended to provide basic installation INSPECTION: GENERAL INSTRUCTIONS: and start-up guidance. It is to be read and thoroughly studied prior to attempting to install or operate any of the equipment supplied. Equipment damage, which occurs by not following these instructions will void the warranty. Upon arrival of pump shipment carefully unpack all components and compare with shipping and purchase order documents to ensure that the order is complete.
GRP Series ELECTRICAL INSTALLATION: GENERAL GUIDELINES All electrical work shall be carried out under the supervision of an authorized, licensed electrician. The present state adopted edition of the National Electrical Code as well as all local codes and regulations shall be complied with. VERIFICATION OF POWER SUPPLY Prior to making any electrical connections or applying power to the pump, compare the power supply available at the pump station to the data on the unit's nameplate.
GRP Series MECHANICAL INSTALLATION: PUMPS WITH AUTOCOUPLING SYSTEMS The HOMA Auto-Coupling is a quick removal system used to prevent personnel from needing to enter the wet well. The HOMA Auto-Coupling kit includes a base elbow, guide claw flange and upper guide rail bracket. The kit also includes a profile seal and base anchor bolts. Refer to “Auto-Coupling Parts ID” technical page on website. 5. Bolt the guide claw flange with rubber gasket to the riser pipe using the SS nuts and bolts provided. 6.
GRP Series INSTALLATION OF PUMPS WITH RING STANDS: Notes: 1. Flange bolts must be tightened in cross pattern to avoid damage to the raise face flanges. 2. Standard Flange Bolts are 316SS 3. Standard Anchors are Plated Steel 4. Autocoupling systems include qty 4 M12 anchors for the upper bracket. Torque to 38 ft#. 5. Anchor bolt holes should be drilled to the actual diameter of the anchor (M12 anchor requires 12mm diameter hole).
GRP Series Installation / Startup Troubleshooting: Listing of Possible Causes: Only authorized service personnel who are trained professionals shall troubleshoot and repair pumps that are experiencing operational or performance difficulties. 1. 2. 3. 4. 5. Incorrect or no power supplied to motor. Power cable cut. Short to ground in cable or motor winding. Control panel circuit breaker open. Actual system head is higher than calculated or All HOMA pumps are factory tested, yet startup specified.
GRP Series PREVENTIVE MAINTENANCE Regular preventive maintenance will help ensure longer pump life and more reliable operation. It is recommended that pumps in intermittent operation be inspected twice a year and pumps in continuous operation be inspected every 1,000 hours. The following is a listing of required inspection and maintenance items. 5. SEAL CHAMBER OIL Caution seal chamber may be pressurized Check the condition of the oil to see if any water leakage has occurred.
GRP Series PROFILE SEAL INSTALLATION When installing a profile seal, one side of the seal has a larger diameter ridge on the outside edge. This side goes to the inside of the guide claw as seen below. Press the seal into its seat starting on one side and work the rest of the seal into the same position. When finished, it should look as below. When properly installed, the profile seal will stay in place when pulled straight outwards.
GRP Series SEAL PROBE INSTALLATION PROCEDURE Mechanical Seal Leak Detection probe has been loose to protect from shipping damage. Please follow this procedure to install the probe. 1) Lay pump on its side with the plug on the seal chamber facing upwards as indicated. 2) Unscrew the plug with the proper wrench, taking care not to damage the sealing surface. 3) Verify that seal chamber oil level is within ¼” of the indicated value. Measurement is from oil level to the top of hole.
