1. High suction range self-priming pump without vacuum assistance (intellectual property certificate number: 2018210770092): A self-priming pump that can have a suction range of 7-8 meters without a vacuum assistance system. After installing a vacuum assistance system, it becomes a high flow high suction range self-priming pump with a suction height (suction range) of up to 9 meters. When the vacuum assist system of the high flow and high suction range self-priming pump malfunctions, the suction range of the high flow and high suction range self-priming pump can also reach 7-8 meters.

2. Fully automatic vacuum assisted diesel engine vacuum assisted self-priming pump (intellectual property certificate number: 2018210769184): The high flow and high suction range self-priming pump is driven by the diesel engine coupling, and the vacuum pump is driven by the diesel engine pulley, with automatic start stop and manual start stop functions.

3. Fully automatic vacuum assisted self-priming pump system (intellectual property certificate number: 2018206318613): Enable the vacuum pump in the vacuum assisted system to have automatic start stop function.

4. The impeller installation base for a pump that can run idle (intellectual property certificate number: 2018210761695): The impeller installation base for a high flow and high suction self-priming pump is equipped with an oil chamber and filled with lubricating oil. When the high flow and high suction self-priming pump starts running idle, the lubricating oil cools and lubricates the mechanical seal and transmission bearings, allowing the high flow and high suction self-priming pump to have the performance of running idle without damaging the mechanical seal, impeller, and pump chamber.

5. Computer Software Copyright Registration Certificate for Water Pump Operation Monitoring and Management System (Registration Number: 2019SR1086864): A high flow and high suction self-priming pump driven by a diesel engine. The start and stop of the diesel engine are both the start and stop of the high flow and high suction self-priming pump; The water pump operation monitoring and management system is a system operation software for diesel engine controllers and vacuum pump controllers, responsible for monitoring and managing various operational indicators of self-priming pumps, vacuum pumps, diesel engines, and ancillary systems.

6. Non clogging self-priming pump impeller (intellectual property certificate number: 2018218353069): The high flow and high suction self-priming pump uses a specially designed semi open self-priming pump impeller from our company, which has non clogging performance and the ability to improve the suction range of the self-priming pump.
