QY submersible drainage irrigation pump

A compact, oil-filled submersible drainage and irrigation pump designed for reliable water transfer in agricultural, municipal and light industrial settings. The unit combines a centrifugal or axial-flow pump section with an oil-filled electric motor below; pump, motor and mechanical seal are integrated into a single, sealed assembly for simple submersion and operation.

Key features

• Fully enclosed mechanical-seal chamber and O-ring sealing provide strong waterproofing and reduce maintenance.
• Oil-filled motor improves motor cooling and prolongs life under submerged conditions.
• Small footprint and light weight allow installation without a dedicated pump room; no priming or additional guide water required.
• Available in cast-iron or stainless-steel wet-end materials to suit freshwater or less demanding environments.

Performance and operating limits

• Designed for use submerged up to 5 m depth.
• Suitable fluid temperature up to 40 °C.
• Maximum suspended solids: approx. 0.1% by weight; maximum particle size approx. 0.2 mm.
• Acceptable liquid pH range: 6.5–8.0.
• Intended media: clean water, well water, river or lake water and similar non-corrosive liquids.

Typical applications

• Well irrigation, sprinkler and drainage systems for farmland and gardens.
• Underground water lifting and water-tower filling.
• Flood and hatch-bottom drainage in marine and coastal applications (subject to material selection).
• Urban construction sites, and industrial/mining supply and drainage where solids and corrosives are limited.

Installation and maintenance notes

• Ensure submerged depth and water quality comply with the stated limits to avoid premature wear of seals and bearings.
• Choose stainless steel wet-end for mildly corrosive or abrasive waters.
• Periodically inspect sealing chamber and power cable entry for wear; follow recommended oil-check and seal inspection intervals.
• Suitable for direct submersion; provide a stable mounting base or guide rail as required for vertical installations.

Materials and configuration

• Pump assembled with integrated pump body, mechanical seal box and oil-filled motor.
• Wet-end material options: cast iron or stainless steel.

This model is intended for businesses seeking a compact, low-maintenance submersible unit for clean-water drainage and irrigation tasks where solids content and corrosivity are limited.
