What Submersible Pumps Does MASTRA PUMP Manufacture? A Full Product Line Overview

When buyers search for a reliable submersible pump manufacturer, the first question is often simple: what exactly does this factory make? For MASTRA PUMP, the answer spans one of the most comprehensive submersible pump manufacturer product lines available from any china submersible pump manufacturer today. Backed by Guangdong Ruirong Pump Industry Co., Ltd., MASTRA PUMP has built its reputation on covering nearly every submersible application—from solar-powered agricultural irrigation to heavy-duty municipal sewage handling. This overview breaks down that MASTRA PUMP product range by category, power, material, and well diameter so you can quickly locate the right product page for your project.

For off-grid and agricultural applications, MASTRA PUMP operates as a dedicated solar and deep well pump factory, producing DC solar submersible pumps alongside AC deep well models. The R85-QS series, for example, represents a 3.5-inch DC solar pump option with max heads reaching 250 meters and flow rates up to 8 m³/h depending on the model . For standard AC deep well duty, the 4-inch R95-ST series covers a broad performance window: the R95-ST2 delivers up to 24 m³/h in certain configurations, with max head capabilities exceeding 400 meters in 60Hz variants . These pumps feature stainless steel 304 pump tubes, 304/316 pump heads, and multistage floating impeller designs that tolerate small sand particles without clogging .

MASTRA PUMP’s sewage lineup addresses the other major submersible demand: moving dirty water without blocking. The MAD series submersible sewage pumps use non-clog impeller designs (E/A/B types) to pass fibrous materials and large solids, with double mechanical seals imported from Italy for wear and heat resistance . At the higher end, the 15 HP sewage pump is built for municipal and industrial wastewater, available in cast iron for abrasion resistance or 304/316L stainless steel for corrosive media such as saline or acidic effluent . This range ensures the MASTRA PUMP product range serves both clean water supply and dirty water disposal within one brand.

Well diameter is often the first constraint buyers face, and MASTRA PUMP organizes much of its deep well offering around this spec. The lineup spans 3-inch, 4-inch, 5-inch, 6-inch, 8-inch, and 10-inch series, with 3SP through 10SP designations appearing across product documentation . The 6SP series, for instance, is a 6-inch stainless steel multistage pump capable of rated flows up to 60 m³/h . The 8SP series serves larger boreholes with all-stainless construction and NEMA-standard motor coupling . For installers, this diameter-based organization simplifies selection: match the well casing, then choose the power and material.
