ZQB-G high-temperature magnetic self-priming pump

The ZQB magnetic self-priming pump is an improvement on the basis of CQB, which combines all the excellent characteristics of magnetic pumps, and its biggest advantage is that it can self-priming without the need for bottom valves and drainage water. The general self-priming height can reach 4-5 meters, fully combining all the advantages of self-priming pumps and magnetic pumps. It not only has self-priming function, but also eliminates shaft seals and uses magnetic coupling for indirect transmission, completely eliminating the phenomenon of dripping. High tech environmentally friendly energy-saving products with leading foreign technology level. Reasonably plan, enhance the universality of components, reduce the number of spare parts and maintenance time. Reserve temperature, vibration, and pressure detection interfaces to enhance the intelligence of pump monitoring and improve equipment reliability. This series of pumps has excellent hydraulic performance, comprehensive spectrum coverage, high efficiency, and high resistance to cavitation. And based on a large amount of experimental data combined with hydraulic analysis software for optimization, its hydraulic performance has reached the current international leading level.

Features: 1. The pump shaft has changed from a dynamic seal to a closed static seal, completely avoiding medium leakage.

2. No need for independent lubrication and cooling water, reducing energy consumption.

3. Add self-priming function, with a suction height of less than 5 meters

4. From coupling transmission to synchronous drag, there is no contact or friction. Low power consumption, high efficiency, and damping effect, reducing the impact of motor vibration on the pump and preventing pump cavitationThe impact of vibration on the electric motor.

Structure Introduction

1、Two static sealing points ensure that even if the internal magnetic rotor components are damaged, there will be no leakage. For extremely dangerous places such as toxic, flammable, and explosive environments, a double isolation sleeve structure can also be used and a leakage alarm device can be installed. Customers can consult our company in detail.

2、The structure is simple and easy to disassemble, providing a more favorable guarantee for uninterrupted operation under working conditions. Our company can send technical personnel to the user's site for training, and customers can also send operators to our company for exchange and learning.
