0.75kW Doyin WSD15-9-0.75C Submersible Sewage Water Pump – 18m³/h Flow, 9m Head, 1HP Motor

Product Overview

The 0.75kW Doyin WSD15-9-0.75C Submersible Sewage Water Pump is built for high-volume, low-head wastewater and drainage applications. Its 750W (1HP) motor delivers a rated flow of 18.0m³/h (18,000L/h) with a 9m head, making it particularly suitable where substantial volumes of wastewater need to be moved over relatively low vertical elevations.

Unlike a conventional clean-water borehole pump, the WSD15-9-0.75C is intended for submerged sewage and wastewater handling, making it practical for drainage pits, wastewater collection points, flooded areas and similar applications.

Macire supplies and verifies Doyin pumping equipment and can assist customers with pump selection based on required flow, discharge head and site conditions.

System Architecture & Configuration

750W / 1HP Motor

The 0.75kW motor provides the driving power required for continuous submerged water movement within the pump’s specified operating range.

18m³/h High-Flow Design

With a rated capacity of 18,000 litres per hour, the pump prioritises water volume, making it suitable for rapid drainage and wastewater transfer.

9m Pumping Head

The 9m head rating makes this model best suited to applications requiring high flow without extreme vertical lifting.

Submersible Sewage Configuration

The pump operates while submerged, allowing wastewater to be pumped directly from pits, sumps and collection points.

Applications / Use Cases

• 🏠 Residential Drainage – Removing wastewater from sumps and collection pits.
• 🏢 Commercial Buildings – Basement, drainage and wastewater pumping.
• 🚜 Farms – Drainage and suitable wastewater-transfer applications.
• 🏭 Workshops & Facilities – Moving collected wastewater and drainage water.
• 💧 Flooded Areas – High-volume removal of accumulated water.
• 🕳️ Sumps & Pits – Pumping water from low-level collection points.

Installation & Engineering Notes

The WSD15-9-0.75C should be installed in a location that allows adequate submersion and unrestricted water entry. The discharge pipe should be correctly sized and routed to minimise unnecessary friction losses.

Because the pump has a 9m head rating, the total dynamic head of the installation should be considered before selection. Excessive vertical lift, long discharge lines, restrictions and fittings can reduce actual flow.

The pump should be lifted using the appropriate lifting arrangement rather than pulling it by its electrical cable. Macire can assist with pump selection based on the site’s required head and flow.

Care, Maintenance & Operations

• Regularly inspect the pump inlet for blockage.
• Keep the discharge pipe free from restrictions.
• Inspect the electrical cable for damage.
• Avoid operating the pump outside its intended submerged conditions.
• Remove accumulated debris around the pump when necessary.
• Check the discharge system for leaks and restrictions.
• Inspect the pump if flow drops noticeably.
• Contact Macire for technical assistance, servicing and compatible accessories.

Do’s & Don’ts

Do’s

• Install the pump fully and correctly in the pumping area.
• Confirm the required head before installation.
• Keep the pump inlet unobstructed.
• Use correctly sized discharge piping.
• Provide suitable electrical protection.
• Inspect the pump periodically.
• Use proper lifting methods when removing the pump.

Don’ts

• Do not pull or lift the pump using its power cable.
• Do not operate with a damaged electrical cable.
• Do not block the pump inlet.
• Do not use undersized discharge piping.
• Do not expect the rated 18m³/h flow at every installation head.
• Do not use the pump for liquids outside its intended application without confirming compatibility.
• Do not operate beyond the manufacturer’s specified limits.

Compatibility

The Doyin WSD15-9-0.75C can be integrated with:

• Sewage collection pits
• Drainage sumps
• Wastewater tanks
• Suitable discharge pipes and hoses
• Non-return valves
• Isolation valves
• Appropriate electrical protection
• Automatic level-control systems where compatible

Performance Guide

Important: Actual discharge flow varies with total head, pipe diameter, pipe length, fittings, wastewater characteristics and installation conditions. A full head-versus-flow curve was not provided, so intermediate flow figures should not be assumed.
