Tianjin Zhijiang Pump IndustryZJ250QJRHot Water Submersible PumpScope of Application
Suitable for farmland irrigation, garden watering, fountain landscapes, rainwater recycling systems, mine drainage, emergency rescue, urban water supply, and extracting underground water sources for enterprises and institutions. The equipment has low noise, high efficiency, and saves electrical energy.
Tianjin Zhijiang Pump IndustryZJ250QJRHot Water Submersible PumpTechnical Parameters:
The outlet diameter is divided into DN80mm, DN100mm, DN125mm. Three diameters. The number of fixed bolts for the unit outlet flange is: 8 pieces, model 14×55 (grade 8.8), bolt center distance 180mm. For user convenience, a matching flange (outer diameter 215mm, inner diameter divided into 3", 4", 5", thickness 18mm) is provided for on-site welding of the pump short pipe by the user.
Tianjin Zhijiang Pump IndustryZJ250QJRHot Water Submersible PumpPermitted Media Range
1: Clear water without impurities, chilled water/cooling water, rainwater, underground water from coal mines, iron mines, metal mines, drinking water, mineral water, etc.
2: Permitted working water temperature range +5 to +25℃
3: Solid impurity content (by mass) not more than 0.01%
4: pH value (acidity/alkalinity) 6.5-8.5 (except for corrosion-resistant materials like stainless steel, tin bronze, etc.)

Tianjin Zhijiang Pump IndustryZJ250QJRHot Water Submersible PumpEquipment Advantages
--Careful assembly in the factory ensures quick and reliable on-site installation.
--Multi-stage impeller design, extremely low noise.
--Built-in check valve to prevent water hammer impact.
--High single-stage head, reducing the overall height of the unit and increasing operational stability. The pump shaft diameter is φ38mm, enhancing the shaft's torsional resistance. The bushings are made of pure natural rubber material for better wear resistance, and are equipped with hard bushings made of imported materials (with added metal outer protective sleeve, a special product).
