MANUFACTURING
From Product Development to Pump Assembly
Product development, tooling, injection molding, assembly and inspection come together at Ningbo Lisheng Pump to support a focused compact pump range.

Manufacturing Capabilities
Product Development, Tooling, Molding and Assembly
The manufacturing workflow is focused on compact submersible pumps and the product requirements agreed for each order.
Product Development
Review the application and define the pump’s performance, construction and electrical requirements.
Tooling Preparation
Plan tooling around the agreed part design and project scope.
Plastic Molding
Produce molded parts for the compact pump range.
Pump Assembly
Assemble the motor, seals, housing and controls to the agreed product specification.
Focused Range
Focused on Compact Submersible Pumps
Our current range centers on plastic-housing pumps, with selected 304 stainless steel housing models. That focus supports model comparison, repeatable product requirements and OEM projects around established designs.
