Product Description
Integrating cutting-edge domestic and overseas technologies, the MDK split-case multistage pump is independently developed for various special operating conditions. Optimized and upgraded according to actual on-site working conditions, it resolves operational failures of equipment in complex environments. Featuring simple operation, stable running and high energy efficiency, it can be equipped with an intelligent control system. It is well-suited for field water supply and drainage projects, and also serves as a preferred option for pipeline leak detection and hydrostatic testing.

Overview
The MDK split-case multistage pump is assembled on a base frame made of angle steel or I-beam. The complete unit can be moved and positioned by crowbars or modern lifting equipment.Thanks to modular design, rapid deployment and reliable performance, it has been widely used across multiple industries. This structure is engineered to enable quick commissioning, easy maintenance and efficient operation, ideal for production sites requiring rapid response and flexible adjustment.
Structural Description
1. Valves, pump and other components are pre-assembled into an integrated unit. No additional valves or instruments are required for connection with other equipment or systems, which greatly simplifies installation.
2. The pump, driver and control system are all mounted on a common skid base and housed inside the pump house. The pump house is fitted with ventilation, cooling and heating systems. As an integrated movable skid-mounted structure, its inlet and outlet pipelines extend outside the house and are connected via flanges. The control cabinet is installed on the base, the switch box on the wall, and all pipelines and valves are fixed on the base. The mobile pump house functions as a complete pumping station with full sets of conveying, control and protection systems.
