Ningguo Kingcool Import and Export Co., Ltd supplies Pump For W/M as part of a one-stop appliance parts program that also covers motors, clutches, inlet valves, hoses and capacitors. We combine in-house metalized polypropylene film capacitor production with a broad sourcing network, so procurement teams can consolidate washing machine components into a single shipment.
Our drain pumps are configured for front-load and top-load machines, aftermarket service distribution and OEM integration. Each unit is built around the machine's drain height, wash temperature, electrical supply and hose interface rather than a single fixed specification.
Drain Pump Range and Application Fit
As a Washing Machine Parts-Pump For W/M Manufacturers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.
The Pump For W/M is a compact centrifugal drain pump mounted at the base of the machine. It evacuates wash and rinse water during drain and spin cycles, and it is engineered for repeated start-stop operation rather than continuous running. Pump cover, plastic-wrapped winding and an integrated thermal protector form the standard build.
- Household front-load and top-load washing machines
- Automatic and semi-automatic models
- Aftermarket replacement and service parts distribution
- OEM integration where mounting and connector interfaces are defined by the machine platform
Critical Specifications We Confirm Before Production
Hydraulic performance, electrical safety and mechanical fit are validated together. A pump that meets the flow target but misses the mounting footprint will not pass line acceptance, so we treat the following parameters as a single configuration set.
| Parameter | Typical Range | Why It Matters |
|---|---|---|
| Flow rate | 20-30 L/min at zero head | Sets drain cycle time and spin performance |
| Head capacity | Up to 1.5 m | Must exceed the installation drain height |
| Power consumption | 25-40 W depending on voltage and load | Affects harness rating and thermal margin |
| Noise level | Below 50 dB(A) at 1 m | Relevant to premium and quiet-cycle platforms |
| Insulation class | Class B or higher with thermal protection | Electrical safety and motor life under repeated starts |
| Water temperature | Up to 90°C | Materials and seals must suit hot-wash programs |
Voltage and Regional Configuration
Drain pumps are supplied in the supply configurations that match the destination market. We confirm the electrical standard together with the connector type so the pump can be fitted without field modification.
Europe, Asia, Africa and Australia service and OEM programs.
North America and parts of South America.
Configured on request for OEM and special projects.
Mechanical and Electrical Configuration Options
Mounting footprints differ between machine platforms, so the pump body, outlet and electrical termination are selected as a matched set. The options below are the variables we adjust most often for replacement and OEM programs.
- Outlet diameter: 18 mm, 20 mm or custom sizes
- Connector type: quick-connect, threaded or hose barb
- Mounting bracket: shaped to the target OEM footprint
- Electrical termination: spade terminals, wire leads or custom harness
- Material changes: available for chemical resistance or higher temperature duty
- Branding and packaging: private label and custom packaging for distribution programs
Quality Control and Acceptance Testing
Our factory uses pressure testing machines, vibration testers, noise analyzers and durability benches. Drain pumps pass through staged checks from incoming material to final packing, and the test record follows the batch.
- Flow and head test to verify hydraulic performance
- Dielectric strength test for electrical safety
- Thermal protection test to confirm the protector activates correctly
- Endurance run of 100+ hours to simulate long-term use
Where a project requires specific compliance evidence, we confirm the applicable standard and documentation scope during configuration rather than assuming a default certificate set.
Installation, Maintenance and Serviceability
The pump mounts to the machine base, connects to the drain hose and plugs into the wiring harness. Installation instructions ship with each unit, and our technical team supports integration questions during commissioning.
- Periodic cleaning of the inlet filter, where fitted, extends service life
- Checking the impeller area for debris prevents reduced flow and noise
- Original spare parts maintain the tested performance of the assembly
Related Washing Machine Parts in Our Range
Drain pumps are usually ordered alongside other components from the same platform. Consolidating them reduces freight cost and simplifies incoming inspection for distributors and service networks.
- Drain motors and inlet valves for the water circuit
- Motors, clutches and gear boxes for the drive train
- Inlet and drain hoses, impellers, rubber seals and drain valve cores
- Capacitors for motor start and run circuits
Our wider catalog also includes Air-Conditioner Parts and Refrigerator Parts for customers who buy across appliance categories.
Information We Use to Configure Your Solution
A quotation is only useful if the pump matches the machine. We prepare the configuration and price from the following project inputs.
- Washing machine brand and model, or the original pump part number
- Voltage and frequency of the destination market
- Required flow rate and drain head
- Outlet diameter and connector type
- Quantity, packaging and branding preferences
- Any specific certification or standard the project must meet
With these details we recommend a standard model or develop a custom build, and we can issue a dimensional drawing for confirmation before production. Inquiries are answered within 12 working hours on business days.
Frequently Asked Questions
What service life can we expect from your drain pump?
Our drain pumps are designed for a service life of over 10,000 cycles, which corresponds to several years of normal household use. The thermal protector and corrosion-resistant materials support long-term reliability under repeated start-stop operation.
Can you supply samples before a bulk order?
Yes. We provide samples in the requested voltage and connector configuration so the fit and drain performance can be verified on the target machine. The sample ships together with a quotation for mass production.
Do you support OEM branding on the pump?
We apply your logo or part number on the pump housing and packaging. Minimum order quantities apply for custom branding, and we confirm the artwork and marking position before production.
How do you confirm the pump fits our washing machine model?
Send the machine brand and model, or the original pump part number. We cross-reference our database and can issue a dimensional drawing for your confirmation before the batch is produced.
What is the lead time for standard configurations?
Standard configurations typically ship 15-25 days after order confirmation, depending on quantity. Custom orders may require additional time for tooling or design changes.
Can drain pumps be combined with other appliance parts in one order?
Yes. As a Pump For W/M supplier, we consolidate drain pumps with motors, clutches, capacitors, inlet valves and hoses so distributors and service networks receive one shipment instead of several.
