Industrial Pumps, Generators & Repairs

For domestic and light agricultural systems, we recommend a professional inspection every 12 to 18 months. Heavy-duty industrial and municipal submersibles should undergo diagnostic checks every 6 months. Regular maintenance—checking current draw, insulation resistance, control panel relays, and dynamic water levels—helps prevent dry-run cavitation and motor winding burnouts, avoiding expensive extraction and replacement fees.

Key warning signs include: 1) A sudden drop in water pressure or flow volume; 2) Metallic grinding or sputtering noises, which typically indicate impeller cavitation or bearing damage; 3) Rapid tripping of your control panel circuit breaker, which suggests motor winding degradation or voltage phase imbalances; and 4) Continuous running without reaching shutoff pressure, often caused by a worn pump wet-end.

Yes, we specialize in classic Lister Diesel motor support across the Eastern Cape. We stock genuine spares including pistons, gasket sets, fuel injectors, high-tensile fasteners, and specialized bronze bushes. Our field engineers can travel directly to your farm or agricultural holding to perform complete on-site mechanical diagnostics and overhauls.

A humming motor that refuses to spin is usually caused by: 1) A locked or scale-clogged impeller (often due to sand or grit ingress); 2) A blown start/run capacitor in single-phase systems; or 3) A single-phasing electrical supply fault (where one of the three phases is lost). Shut down the power grid immediately to prevent thermal overload and stator coil damage, then call our workshop for diagnostic assistance.

Standard electric motor rewinding and impeller replacements are completed within 24 to 48 hours at our state-of-the-art East London workshop. For critical situations, we offer expedited 24/7 priority emergency services to restore water flow or electricity grids swiftly in compliance with our strict SLA response commitments.

Absolutely. All newly supplied pumps, Lister engines, and comprehensive overhaul projects come with a solid 12-month SANS-compliant warranty covering both components and technical workmanship. Every overhauled pump is subjected to rigorous hydraulic and electrical load-testing on our test rigs before being cleared for field deployment.
