Product Overview

The F2251E-MK magnetic regenerative turbine pump is designed for compact industrial circulation systems that require controlled liquid transfer at elevated temperatures. Its sealless magnetic drive separates the motor from the pumped liquid and removes the conventional rotating shaft seal from the pump structure.

This model can be used for circulating hot water and heat-transfer oil in temperature-control equipment, heating systems and industrial machinery. Buyers should select the motor power and operating configuration according to the required flow, head, medium and temperature.

How to Select the Correct Model

Before requesting a quotation, please provide the required flow rate, total head, liquid name, operating temperature, viscosity, voltage, frequency and phase.

The maximum flow and maximum head are not normally achieved at the same operating point. The performance curve should be checked when selecting a pump for continuous operation.

For low-temperature liquids, corrosive chemicals or special system pressures, please provide complete operating conditions for technical confirmation.

Wholesale and OEM Supply

FENGHE supplies magnetic pumps to overseas importers, distributors, equipment manufacturers, system integrators and OEM buyers. Different motor powers, frequencies and connection configurations can be discussed according to the application and order requirements.

Final specifications, voltage, packaging and OEM requirements should be confirmed before production.

Frequently Asked Questions

What liquids can the F2251E-MK pump handle?

It is designed mainly for hot water and heat-transfer oil circulation. Other liquids require compatibility confirmation.

What is the maximum operating temperature?

The available data shows a maximum of 180°C for water and 350°C for heat-transfer oil. Actual selection depends on the medium and operating conditions.

Which motor powers are available?

The listed motor power options are 0.25 kW, 0.37 kW and 0.50 kW.

Is the pump completely leak-free?

It uses a sealless magnetic drive structure that removes the conventional rotating shaft seal. Proper installation and operating conditions are still required.

Can you supply a pump for low-temperature service?

Low-temperature configurations may be available, but the required temperature, medium and model must be confirmed before selection.
