JS JST 316 Stainless Steel Drainer Submersible Pump GFM-100 (230V) — JSPump

Model: GFM-100 | Brand: JSPump | SKU: 011-780. The JS JST GFM-100 is a heavy-duty 316 stainless steel submersible drainer pump engineered for demanding drainage and dewatering tasks. Built from precision-cast AISI 316 stainless steel, the unit offers excellent corrosion resistance for seawater, effluent and light chemical applications — ideal for industrial, marine, construction and commercial sump pumping.

Designed for reliable submersible operation, the pump is specified to deliver approximately 350 L/min at a 5 m head and runs on 230V power — a compact, efficient solution for washdown sumps, chemical sumps and water remediation. Its robust wet-end construction and corrosion-resistant components make it suitable for prolonged exposure to aggressive liquids.

Key features

• 316 stainless steel body, impeller and shaft for superior corrosion resistance.
• FKM (Viton) elastomers and O‑rings for chemical and fuel resistance.
• Twin mechanical seals (carbon ceramic & silicon carbide) in a lubricated chamber for extended seal life.
• Complete with long power cable (typically 10m) and hose tails; guide-rail mounting options available for easy service.
• Capable of handling small solids and typical drainage debris — suited to dewatering, effluent transfer and seawater applications.

This submersible drainer pump balances high flow performance with corrosion-resistant construction and serviceable mechanical sealing.
