Used Graco Pumps in Michigan, USA

Overview

Pumps move liquids, slurries and wastewater for construction, dewatering, irrigation and industrial processes. Common types include centrifugal, submersible, diaphragm and positive-displacement pumps. Key selection factors are flow rate, total head, material compatibility, seal type and power source (diesel engine, electric motor, hydraulic). Used pumps are often skid- or trailer-mounted for jobsite mobility and should be checked for corrosion, wear and seal integrity before purchase.

FAQ

What specifications should I check when buying a used pump?

Verify flow (GPM/lpm), total head (ft/m), pump curve, material compatibility, seal type, drive power and any accessory items like priming systems or control panels.

How do I assess the condition of a used pump?

Inspect for corrosion, shaft runout, seal and bearing wear, impeller damage and evidence of cavitation. Check engine hours and service records if it’s engine-driven.

What shipping preparations are needed for pumps?

Drain all fluids, secure moving parts, protect shafts and flanges, bolt units to skids or crating, and declare any hazardous residues. Note weight and dimensions for transport equipment.

How should I plan power and mounting on arrival?

Confirm coupling type (direct, flexible, belt), driver compatibility (engine vs electric), foundation or skid requirements, and alignment procedures before installation.

What routine maintenance keeps a pump reliable?

Regularly check seals and packing, monitor vibration and bearing temperature, inspect impeller and casing, change lubricants, and follow manufacturer service intervals.

How important is spare parts availability?

Critical. Ensure common spares (mechanical seals, bearings, impellers, gaskets) are available or compatible parts can be sourced to minimize downtime.
