MASTRA PUMP (Guangdong Ruirong Pump Industry Co., Ltd.) is a factory-direct OEM submersible pump manufacturer offering full customization across power ratings from 2 HP to 15 HP. Brands and distributors can specify motor power, voltage configuration, materials, outlet diameter, and cable length — all produced under one roof with over 33 years of manufacturing experience and an output exceeding 80,000 units per month.
Whether you are a regional distributor seeking private label well pumps or a brand looking to differentiate with custom submersible pump specifications, this guide explains exactly what MASTRA PUMP can customize, why factory-direct OEM sourcing matters, and how to get started.
OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) submersible pump manufacturing means a factory produces pumps to a buyer's exact specifications — including branding, technical parameters, and packaging — rather than selling off-the-shelf stock.
OEM is best suited for brands or distributors that already have defined product specifications and want a manufacturer to produce units under their label.
ODM works best when a buyer needs the manufacturer to contribute to product design and then produce the finished goods under a private label.
MASTRA PUMP supports both models, making it a flexible partner for brands at any stage of product development.
Sourcing directly from a manufacturer — rather than through a trading intermediary — provides measurable advantages for brands and distributors:
Lower unit cost: No middleman markup; factory pricing applies directly.
Faster lead times: Production scheduling, quality checks, and shipping are managed in-house.
Tighter quality control: MASTRA PUMP operates its own production facility covering more than 60,000 square meters, with over 100 honors and certificates earned across 33+ years of operation.
Custom branding: Private labels, custom packaging, and documentation can be arranged directly with the factory team.
Technical accountability: Engineering and quality teams are accessible for pre-production discussions, specification reviews, and after-sales support.
For brands scaling distribution across 120+ export markets — as MASTRA PUMP already serves — working directly with a manufacturer eliminates the ambiguity and added cost that trading companies introduce.
MASTRA PUMP supports a broad range of technical customizations for submersible pumps in the 2 HP to 15 HP segment. Buyers can specify:
Parameter | Available Options |
|---|---|
Motor Power | 2 HP – 15 HP |
Voltage / Frequency | Single-phase or three-phase; 50 Hz or 60 Hz |
Casing Material | Stainless steel (304 / 316L) or cast iron |
Pump Diameter | 3 inch, 3.5 inch, 4 inch, 4.5 inch, 5 inch, 6 inch, 8 inch, 10 inch |
Outlet Size | Customized to project requirements |
Cable Length | Adjustable to installation depth |
Branding | Private label / OEM nameplate |
Packaging | Custom box design and labeling |
Stainless steel options — particularly 304 and 316L grades — are well suited for corrosive environments such as mining, seawater proximity, or chemical-adjacent applications. Cast iron variants offer a cost-efficient alternative for standard agricultural and residential well applications.
MASTRA PUMP's catalog spans multiple series, each available for OEM customization:
The R-Series (R75, R85, R95, R110, R125, R150) and SP-Series (3SP through 10SP) cover a wide power and flow range. The 4 inch R95 Series and the 6 inch SP30/SP46/SP60 Series are among the most commonly requested for OEM orders.
Available in both 50 Hz and 60 Hz configurations, MASTRA submersible motors can be paired with pumps or supplied independently for OEM motor-only contracts.
The solar pump system range is available for OEM customization, including controller integration — particularly relevant for off-grid agricultural and rural water supply projects.
Sewage pumps and multistage centrifugal pumps round out the portfolio for buyers seeking a broader product line under a single private label.
Submit technical specifications — power range, voltage, material, outlet size, and annual volume — to the MASTRA PUMP team via the contact page or by emailing ruirong@ruirong.com.
MASTRA PUMP's engineering team reviews the specifications and provides a factory-direct quotation, including lead time estimates based on current production capacity.
A pre-production sample is manufactured to confirm specifications, labeling, and performance benchmarks before full production begins.
All units are produced in MASTRA PUMP's Guangdong factory, where in-house quality checks are conducted prior to shipping. With an 80,000+ unit monthly output, large-volume orders are handled efficiently.
MASTRA PUMP exports to 120+ countries. Shipping documentation, certifications, and logistics coordination are managed to meet destination market requirements.
