Why Choose the Sulzer JC 34 Submersible Pump?
Slim, center‑line design ideal for installations with limited space, especially trenches or confined sumps.

Plug‑and‑pump setup allows immediate start without external starter panels, with built‑in thermal protection to prevent motor overheating.

Designed for pumping water and lightly abrasive dirty water reliably—even at low water levels or during occasional dry running.

High wear resistance provided by high‑chrome alloy steel impeller and nitrile‑coated diffuser components—ensures long service life.

Modular construction facilitates on‑site servicing; top cover access to the electrical junction box and safe oil casing for seal inspection.

Key Design Features
Robust motor protection through thermal switches (≈ 140 °C) wired to an internal contactor for automatic restart.

Durability-focused hydraulics: white cast‑iron impeller and wear ring, excellent heat convection via dual casing for low‑water/dry operation.

Service‑friendly layout: easy access to electrical junction box, seal inspection via oil casing, modular hydraulic units for flexible configuration.

Wear-resistant materials throughout ensure consistent pumping performance in abrasive or dirty water contexts

The Sulzer JC 34 is a powerful yet compact dewatering pump , engineered for light abrasive dirty water applications where space is constrained but high performance is necessary. Its high‑head and high‑flow capability , combined with built‑in protection, efficient hydraulics , and modular servicing , make it a durable and user‑friendly choice for trench draining, utility pits , and construction dewatering projects.
