Grindex Pumps FAQ
What Grindex pumps are featured?
The page focuses on drainage, sludge, slurry, and corrosion-resistant submersible options for demanding dewatering applications.
How does a drainage pump differ from a slurry pump?
The expected particle load and abrasion influence their construction. Select for the actual solids size, hardness, and concentration rather than treating all dirty-water duties alike.
What information is needed for construction-site dewatering?
Provide expected inflow, discharge elevation and distance, solids, water chemistry, and available power. Include likely changes in pit depth or water level.
Can Grindex equipment be considered for mining water?
Suitable models can be evaluated for mine drainage or abrasive service. Describe chemistry and solids so the model and materials can be matched to the conditions.
When should corrosion-resistant construction be evaluated?
Consider it when water chemistry attacks standard materials. Stainless steel is not universally compatible, so provide chemical composition and temperature.
Why does discharge hose length affect pumping capacity?
Hose friction and elevation increase the head the pump must overcome. Use the actual route, diameter, and fittings when estimating the available flow.
How do I size a submersible pump?
Use required flow, total discharge head, liquid characteristics, and the operating cycle. Include elevation, pipe friction, and the lowest expected liquid level when reviewing the pump curve.
Why is my pump running without lowering the liquid level?
Inflow may exceed capacity, or the discharge may be restricted. Worn components, an obstructed inlet, air locking, or incorrect rotation can also reduce pumping performance.
Why does a submersible pump keep clogging?
Solids, fibers, and debris may exceed the pump's handling capability. Review the actual waste stream, inlet conditions, and hydraulic selection before assuming a larger motor will solve the problem.
Why is my pump tripping its breaker or overload?
Obstructions, motor faults, cable damage, or supply problems may be involved. Have qualified personnel investigate the fault; repeated resetting can conceal a developing equipment problem.
Can a submersible pump operate with the motor exposed?
The answer depends on its cooling arrangement and duty rating. Check minimum liquid level and operating limits for the exact model rather than assuming all submersible pumps can run uncovered.
How often should submersible pumps be inspected?
Follow the manufacturer's schedule and consider solids, runtime, and service history. Include cables, seals, hydraulic components, level controls, and alarms in the maintenance plan.
What can cause frequent starting and stopping?
Float placement, changing inflow, check-valve leakage, or insufficient working volume may contribute. Review the control sequence and permitted starts per hour before changing the installation.
Can a damaged submersible pump be rebuilt?
Inspection should assess the motor, seals, cable entry, and hydraulic parts. Compare repair cost and downtime with replacement, especially if the fluid conditions have changed.
How can I get local support for Grindex Pumps?
Contact Process & Power at (901) 362-5500 with your location, equipment identification, and application or service concern. The team can review selection, parts, and service options for your needs.
What should I send when requesting a quote?
Include the required duty, fluid or process details, operating conditions, utilities, and installation dimensions. For existing equipment, add nameplate photos, model and serial numbers, and a description of the problem or planned change.
