The 1 invention patent and 5 utility model patents obtained this time are not only expanded the patent matrix of Credo Pump, but also improved the mixed flow pump and vertical turbine pump in terms of efficiency, service life, accuracy, safety and other aspects. Optimization of various types of water pumps and components such as pumps and fire pumps has further promoted the high-quality innovative development of China's water pump industry.

The details of the 6 patents are as follows:

1. Self-balancing Multistage Split Case Pump 

The patent of this invention provides a new type of single-suction multi-stage split case pump with novel structure, low difficulty in casting and processing, stable product performance, high efficiency, and convenient installation and maintenance. It solves the problems of difficult maintenance and extremely inconvenient maintenance of conventional segmented multi-stage centrifugal pumps. It also solves the disadvantages of volute-type multi-stage split pumps that increase the difficulty of casting and processing of products due to the complexity of the flow path. The newly invented automatic balanced multi-stage split case pumps can effectively extend pump service life and reduce pump production, operation and maintenance costs.

2. Mixed Flow Pump

This newly invented mixed flow pump changes the seal at the impeller inlet from a conventional arc surface seal to a cylindrical surface seal, effectively avoiding the need to repeatedly adjust the axial installation size of the impeller assembly to control the impeller assembly and bell mouth structure. The gap between them solves the problem of complicated product installation, reduces the risk of friction between the impeller assembly and the bell mouth structure, and thereby improves the hydraulic efficiency and service life of the mixed flow pump.

3. Impeller Shaft Assembly & Fire Pump

This impeller shaft assembly is mainly composed of a transmission wheel and an impeller assembly. The new design not only improves the safety of the pump, but also reduces manufacturing costs.

4. Positioning Device for Welding the outlet Elbow of Vertical Turbine Pump

The use of this positioning device can not only quickly and accurately position and adjust the distance between the parts to be welded in the axial direction; it can also quickly and accurately position and adjust the distance between the parts to be welded and the reference axis. This reduces the difficulty of positioning and adjusting the parts to be welded and improves the positioning accuracy of the parts to be welded.

5. Device for Marking the Elbows of outlet Elbows in Vertical Turbine Pump

When this marking component moves to the target position, it can fit into the elbow and rotate around the main axis to mark the elbow, which can not only improve the efficiency of marking, but also accurately mark out the appropriate shape. This improves the efficiency and accuracy of marking the water outlet elbow.

6. Rotating Components for Plate Rolling Machines & Plate Rolling Machines

The rotating assembly of the newly developed plate bending machine developed by Credo Pump includes the first limiter, the second limiter, fasteners and rotating parts. It can reduce the degree of plate wear to improve the dimensional accuracy of plate formed parts and the probability of damage to the plate bending machine.

In particular, the newly developed new single-suction multi-stage split  case pump takes into account multiple features such as low processing difficulty, stable product performance, high efficiency, and convenient installation and maintenance. It can effectively extend the service life of the product and reduce product production, operation, and maintenance costs.

New achievements inspire new journeys, and new journeys create new brilliance. Credo Pump's R&D expenditure has accounted for more than 5% of sales revenue for several consecutive years. It currently has 7 invention patents, 59 patent certificates, and 3 soft copies.
