The low-power 304 Vertical Submersible Pump is entirely made of AISI 304 stainless steel (including the pump body, impeller, motor housing, and shaft core). The motor is sealed integrally with the pump body and works vertically and vertically submerged in water. The vortex or single-channel impeller allows the passage of solid particles ≤ 10–20 mm. It is suitable for pumping clear water, rainwater, and slightly contaminated water (pH 5–9), and is widely used in household rainwater collection, basement/closet drainage, small catch basins, aquarium circulation, garden irrigation, small industrial cleaning, fountain landscaping, etc.
Products features
Whole machine 304 stainless steel: The pump body, impeller, motor housing, and shaft core are all made of AISI 304 (EN 1.4301) stainless steel. Their corrosion resistance far exceeds that of cast iron submersible pumps, and they are suitable for rainwater, groundwater, slightly polluted water, and seawater environments.
Coaxial integrated vertical submersible structure: The motor is located at the top of the pump, while the water pump is at the bottom. They are connected coaxially and sealed together. The entire machine is vertically submerged in water, and the motor is cooled by the surrounding flowing liquid.
Double end-face mechanical seal + oil chamber: Double hard alloy mechanical seal, with an oil chamber in the middle for isolation. It separates the motor chamber from the sewage water, ensuring long-term reliable IP68 protection.
Built-in thermal protector: The motor winding is equipped with a thermosensitive element. Overload or overheating will automatically shut off the power, and it will automatically reset after cooling to prevent damage.
Rotary flow/Single flow channel impeller: It can pass through ≤10–20 mm solid particles (depending on the model), and it can handle slightly contaminated water without clogging.
Application scenario
ow-power 304 Vertical Submersible Pump Features "304 stainless steel corrosion resistance + low power consumption single-phase electricity + vertical compact design", and performs exceptionally well in the following scenarios:
Domestic rainwater collection: Pressurized delivery of rainwater from barrels or tanks to garden irrigation pipelines
Basement/closet drainage: Emergency pumping of floodwater, basement leakage
Small catchment wells: Well water extraction for single-family homes and villas
Small industrial cleaning: Fresh water supply for workshop floor rinsing and equipment cleaning
Fountains and landscapes: Small fountains, water feature circulation, artificial waterfalls
Construction sites: Shallow foundation well drainage, construction wastewater pumping (lightly contaminated water)
Supplier Introduction
