Product Summary

The WQD Sewage Submersible Pump from ZHEJIANG CGO CO.,LTD. is a cast iron electric submersible pump built for reliable sewage and wastewater transfer across residential, commercial, and construction environments. Combining a heavy-duty cast iron body with a single-phase or three-phase asynchronous motor, the WQD sewage water pump handles liquid temperatures up to 60°C at immersion depths up to 5 meters. Available in five models from 0.55 kW to 1.1 kW, this submersible sewage pump series covers flow rates of 6 to 15 m³/h and heads up to 16 meters — a practical range for drainage, sump pit management, and wastewater transfer applications where dependable performance matters.

Detailed Description

At its core, the WQD sewage submersible pump is a fully submerged electric pump unit that integrates the water pump, mechanical seals, and motor into one compact assembly. This design gives the submersible sewage pump its well-known installation advantages: no separate priming line, no above-ground motor mounting, and a significantly smaller footprint compared to end-suction dry-installed pumps.

ZHEJIANG CGO CO.,LTD. builds the WQD electric submersible pump with a cast iron pump body, cast iron impeller, and cast iron motor housing. This material choice is a deliberate engineering decision — cast iron offers better resistance to the wear and gradual corrosion that comes with continuous sewage service, compared to lower-grade housing materials commonly used in budget-tier pumps. The motor shaft uses 45# steel for its combination of tensile strength and machinability.

The mechanical seal uses a ceramic/graphite face pairing — ceramic on the static ring, graphite on the rotating face. Graphite is self-lubricating, which reduces heat buildup at the seal interface during extended run cycles. The result is a submersible sewage pump seal that holds up through the kind of duty cycling found in residential sump systems, commercial basement drainage, and light industrial wastewater collection.

Key Product Features

• Cast iron pump body, impeller, and motor housing for long-term sewage service durability

• Ceramic/graphite mechanical seal for reliable shaft sealing in wastewater environments

• IPX8 waterproof rating supports full submersion operation in continuous S1 duty

• Class B insulation motor with thermal margin suitable for 60°C liquid temperatures

• Single-phase or three-phase power: 220V/50Hz standard; 110V/60Hz and 220V/60Hz on request

• 8-meter pre-installed power cable for direct pit installation without cable extensions

• Uniform 2-inch outlet across all five models for standardized pipeline connections

• Compact 470×250×235 mm body fits standard sump and collection pit dimensions

Engineering Advantages

The WQD submersible sewage pump series covers five distinct performance points without changing the physical envelope. All five models share the same 470×250×235 mm body dimensions and 2-inch outlet — meaning spare parts, installation brackets, and discharge pipework can stay standardized across an entire fleet of WQD sewage water pumps running at different flow and head requirements. That consistency is a real advantage when managing multi-site installations or running a service inventory.

The motor carries an IPX8 protection rating, confirming continuous submersion capability beyond 1 meter — the WQD sewage submersible pump is rated to 5 meters, comfortably within that range. Class B insulation supports winding temperatures up to 130°C, providing adequate thermal margin even when the pumped liquid is at the rated 60°C limit.

For buyers evaluating power supply compatibility across different markets, ZHEJIANG CGO CO.,LTD. offers the WQD electric submersible pump in 110V/60Hz and 220V/60Hz configurations on request alongside the standard 1∼220V/50Hz setup — covering most regional grid standards without requiring rewiring or transformer adapters on site.

Primary Applications

The WQD cast iron sewage pump is widely used across industries and installation types:

• Residential: basement sump drainage, garden runoff management, greywater transfer

• Commercial buildings: underground carpark drainage, hotel facility maintenance, toilet wastewater lift stations

• Construction sites: groundwater removal from excavations, surface water clearance during foundation work

• Light industrial: factory floor drainage, workshop effluent transfer, process water collection

• Municipal: portable emergency drainage deployment, small-scale sewage collection, stormwater management

Commercial Value 

For procurement teams, distributors, and project contractors sourcing submersible sewage pumps at volume, the WQD series from ZHEJIANG CGO CO.,LTD. delivers a clear operational advantage: all five models share the same physical envelope and outlet size. That uniformity keeps logistics, installation labor, and replacement parts management straightforward across multi-site deployments — one bracket design, one outlet fitting spec, one service procedure for the entire range.

The cast iron construction and IPX8-rated motor make the WQD sewage submersible pump a durable option that holds up longer in demanding drainage environments. For B2B buyers managing pump populations across residential, commercial, or municipal contracts, that durability directly lowers the lifecycle cost per installed unit and reduces unplanned service callouts.

FAQ

Q: What types of liquid is the WQD sewage submersible pump suitable for?
A: The WQD submersible sewage pump is designed for wastewater, sewage, and lightly contaminated water with fine suspended solids. It is not intended for highly abrasive slurry or large solid particles — for those applications, a higher-clearance sewage pump would be more appropriate.

Q: What is the maximum immersion depth?
A: The WQD cast iron sewage pump is rated for up to 5 meters immersion depth. The pre-installed 8-meter cable covers this depth with cable to spare for routing to the surface junction box.

Q: Can the WQD sewage pump operate continuously?
A: Yes. The motor is rated S1 duty, which covers continuous operation. For intermittent-duty cycling applications, the motor’s thermal reserve provides adequate headroom at the rated load.

Q: What voltage configurations are available?
A: Standard is 1∼220V/50Hz. ZHEJIANG CGO CO.,LTD. also supplies 110V/60Hz and 220V/60Hz on request, covering grid requirements across North America, Europe, and Asian markets.

Q: Do all five WQD models share the same dimensions?
A: Yes. All models — from WQD6-12-0.55F through WQD15-9-1.1F — share the same 470×250×235 mm body and 2-inch outlet, simplifying installation templates, storage, and parts management across mixed fleets.
