2HP 3HP Explosion-Proof Submersible Sump Pumps Low Head High Discharge Pump For Sewage Water

The WQB35-7-2.2 is an efficient submersible pump designed to meet low flow requirements, suitable for various applications such as light industrial drainage, wastewater treatment, and agricultural irrigation. This pump offers a maximum flow rate of 35 cubic meters per hour (m³/h) with a head reaching up to 7 meters, powered by a robust 2.2 kW motor, ensuring stability and efficiency when handling fluids containing a small amount of suspended particles. The overcurrent components can be made from high-quality materials like 304 or 316 stainless steel, providing excellent corrosion resistance, making it ideal for long-term reliable operation even in environments with chemical substances.

The WQB35-7-2.2 features an optimized hydraulic design that effectively reduces the risk of clogging and enhances overall efficiency. It also comes equipped with high-performance mechanical seals to ensure leak-free operation, thereby reducing maintenance frequency and extending the lifespan of the pump. To further enhance reliability, users can opt for an intelligent monitoring system that provides real-time data on critical parameters such as temperature, pressure, and vibration. This enables preventive maintenance, minimizing downtime due to unexpected failures. The compact design facilitates easy installation and maintenance, making it particularly suitable for use in space-constrained settings.

FAQ
 

Q1: What is the noise level of the WQB series pumps?
A: The WQB series pumps feature a quiet design, resulting in lower noise levels during operation. The exact noise value depends on the model and working conditions.

Q2: What should you do if the pump does not start?
A: First, check if the power connection is normal and if the fuse is intact. If everything is fine, it may be due to motor failure or control system issues. It is recommended to contact professional repair personnel for detailed inspection.

Q3: Can the WQB series pumps handle fluids containing solid particles?
A: Yes, the WQB series pumps are designed with special hydraulic structures that can effectively handle fluids containing a certain proportion of solid particles, but it is important not to exceed the maximum allowable particle size.

Q4: How do you correctly install the WQB series pumps?
A: During installation, ensure that the pump body is vertically placed in the liquid and that the power cables are connected properly. It is recommended to follow specific application conditions and the manufacturer's guidelines for installation.

Q5: Can the WQB series pumps be used in corrosive liquids?

A: Yes, WQB series pumps can be made of corrosion-resistant materials such as 304 or 316 stainless steel, and key flow-through parts can also be replaced with high-chromium alloy materials, which can be used for a long time in liquids containing a certain concentration of corrosive substances. However, for particularly strong corrosive media, specific material selection is recommended.
