Relong Submersible Slurry Pump

Product catalog summary
Main Features
The submersible slurry pump series offers significant advantages over traditional slurry pumps, including high slag suction efficiency, thorough dredging without suction lift restrictions, and reduced investment costs due to the absence of auxiliary vacuum pumps. The operation is simplified as no auxiliary mixing devices are needed, and the underwater motor can be easily inserted without complex ground protection. The mixing impeller's direct contact with the deposition surface allows flexible concentration control. The equipment operates quietly and vibration-free, maintaining a tidy site as it is submerged in water.
Conditions of Use
The pumps require a 50Hz, 380V three-phase AC power supply. The medium temperature should not exceed 60°C and must be free of combustible or explosive gases. The maximum solid particle concentration is 30%, with a medium density limit of 1.2kg/L. Diving depth ranges from 20 to 150 meters, with vertical operation in the medium being optimal for continuous operation. Customizations are available for non-standard site conditions.
Performance Parameters
The document includes a detailed table of ZJQ performance parameters, covering models, outlet diameters, flow rates, head, motor power, rotating speed, maximum granularity of interrupted passing, and weight for various models.
WQ Non-Clogging Submersible Sewage Pump
This pump features a compact structure and small footprint compared to general horizontal or vertical sewage pumps. It offers convenient installation and maintenance, often with automatic coupling devices, and allows for long continuous operation due to its coaxial pump and motor design. It avoids cavitation damage and irrigation issues, with low vibration and noise, and minimal motor temperature rise.
Seal Types
The document describes various seal types used in the pumps, including the Gland Shaft Seal, suitable for all operating conditions with PTFE and graphite options; the Expeller Seal, which uses pressure seal produced by impeller and expeller in series; and the Mechanical Seal, an international leading sealing technique with no leakage, featuring a cartridge structure for easy installation.
Material and Construction
The pumps are constructed using high hardness ceramic and alloy materials for friction parts, designed for high abrasive resistance and shake-proof characteristics. The mechanical seals and sealing boxes are tailored for fluid states to ensure customer satisfaction in diverse conditions.
Quality System
The company employs a range of universal and specialized analyzer measuring tools, including ultrasonic flaw detectors, photoelectric direct reading spectrometers, metallographic analyzers, universal material testers, impact testers, pressure testers, and hardness scales. A professional test station for pumps is established to conduct comprehensive inspections of materials, microstructures of raw materials, parts machining, pump assembly, and product performance.

Relong Submersible Slurry Pump-1

Submersible Slurry Pump MAIN FEATURE Compared with the common slurry pump, the series products have the foll wing features ①It' s not restricted by suction lift, the slag suction efficiency is high,and dredging is more thorough. ②It is not required to equip the auxiliary vacuum pump, and the investment is more inexpensive. ③It is not required to equip the auxiliary mixing device, and operation is simpler. ④It is not required to build the complicated ground protection and fixing device when the motor is inserted under water,which is simple and convenient. ⑤The mixing impeller directly contacts the deposition surface, and the depth is controlled through the submerged depth.Therefore,concentration control is more free. ⑥The equipment is directly inserted into water for work,there is no noise or vibration, and the site is more tidy. CONITION OF USE ①The power supply is 50Hz,380V three-phase AC supply. ②The medium temperature shall not be higher than 60℃,and the medium shall not include the combustible and explosive gas. ③The maximum weight concentration of solid particle in the medium is 30%, and the maximum medium density is 1.2kg/L. ④The maximum diving depth of the unit can generally reach 20-150 meters.The minimum diving depth is based on the submerged motor. ⑤The unit shall operate in a vertical way in the medium at best, and the operation mode is continuous operation. ⑥When the site conditions do not conform to the above provisions,please indicate it during order. It can be customized acc

WQ non-clogging submersible sewage pump Advantages ü Compared with general horizontal pumps or vertical sewage pumps, the sewage pump has a compact structure and a small footprint. ü Installation and maintenance are convenient. Large sewage pumps are generally equipped with automatic coupling devices for automatic installation. Installation and maintenance are quite convenient. ü Long continuous operation time. Since the sewage pump and the motor are coaxial, the shaft is short, and the weight of the rotating parts is light, the load (radial) on the bearing is relatively small, and the service...
