Products Description

MDLK Submersible multistage pump is a non-self-priming vertical multistage centrifugal pump designed for use with a standard motor. The motor shaft is directly connected to the pump shaft through a coupling in the pump head. The pump can also be equipped with an intelligent protection device as needed, providing effective protection against dry running, phase loss, overload, and other operating faults.

To meet different installation depths for tanks or containers, a chamber section can be added to adjust the overall length of the pump.

Features

Advantage

Flexible Multistage Configuration

The MDLK series designed as submersible multistage pump and features a modular design for precise head matching. The number of stages can be adjusted to meet specific pressure and head requirements.

Motor Configuration

We offer 2-pole IE3 motor for standard, and more than 5 motors options for different requirments.

High-Protection Terminal Box

The terminal box interface features a tongue-and-groove joint to enhance sealing integrity and overall protection rating.

Quick-Service Coupling Design

The pump head utilizes a separate coupling structure from the motor, facilitating rapid installation and effortless maintenance of the mechanical seal.

FAQ

Q: What is a Submersible multistage pump mainly designed for?

A: A Submersible multistage pump is built to operate fully underwater while delivering higher pressure through multiple impellers. It is often used in deep wells, boreholes, and water supply systems where water needs to be lifted from lower levels to the surface.

Q: How is it different from a Horizontal inline pump?

A: A Submersible multistage pump works underwater and pushes water upward, while a Horizontal inline pump is installed directly in a pipeline and handles flow within a system. They serve very different installation setups and are chosen based on where the water source is located.

Q: Can a Submersible multistage pump be used for deep water applications?

A: Yes, that's one of its main purposes. It is commonly used in deep wells and underground water sources where standard surface pumps cannot reach or perform efficiently.
