1 model magnetically driven no shaft seal
Thermal Oil And Hot Water Pumps To 350 Degrees
Heat transfer pumps for hot water and thermal oil circuits, magnetically coupled so there is no shaft seal to fail at temperature.
The Range
The LP2251 Heat Transfer Pump
Four motor ratings cover the common small circuit duties: 90 W at 8 m head, 180 W at 20 m, 370 W at 35 m and 500 W at 40 m.
Who Buys This Line
- Builders of thermal oil heating systems for presses and reactors
- Plating and galvanising lines with heated tanks
- Printing, film processing and textile plants with hot circuits
- Food and pharmaceutical plants running hot water loops
Problems It Solves
Seals fail at temperature
Hot oil destroys ordinary shaft seals. This pump has no shaft seal at all: magnetic force carries the drive through a closed housing.
Leaks of hot oil are a fire risk
A closed pump head removes the leak path that makes a hot oil circuit dangerous to run unattended.
Water pumps cannot take the heat
Standard water pumps stop around 80 degrees. This line is rated for heat transfer duty up to 350 degrees.
Why This Line
Why A Magnetic Drive On Hot Duty
No Axis Seal
Magnetic coupling means nothing rotates through the housing wall, which is what removes the leak and the maintenance item.
Two Speeds
1400 and 2800 rpm builds let the circuit be matched without throttling the line.
Small Circuit Sizes
Ratings from 90 W to 500 W cover the pump sizes that thermal oil skids and heated tanks actually need.
Application Scenarios
Where These Pumps Run
Thermal Oil Circuits
Circulating heat transfer oil between a heater and a press, reactor or drying tunnel.
Hot Water Loops
Moving hot water through a process at temperatures that would end a standard pump seal.
Plating And Developing Lines
Galvanising, film developing, printing and textile lines where hot liquid runs continuously.
Industries Served By This Line
Selection Guide
Choosing A Heat Transfer Pump
State The Fluid And Temperature
Hot water or thermal oil, and the working temperature. The pump is rated for low corrosive hot liquid without solids.
Fix Flow And Head
The four builds run from 10 L per minute at 8 m to 30 L per minute at 40 m. Circuit resistance decides which one.
Confirm The Supply
Single phase or three phase at 220 to 240 V, and which speed the circuit suits.
Check Circuit Protection
Thermal oil circuits need expansion and protection devices. Tell us the system layout so the pump is quoted into it correctly.
Answers
High Temperature Pumps FAQ
How hot can the liquid be?
The heat transfer pump range is rated to 350 degrees Celsius for hot oil duty. For lower temperature hot water circuits the same magnetic drive principle applies.
Why is there no shaft seal?
The motor drives the impeller through a magnetic coupling, so no shaft passes through the housing. That removes the seal, the leak path and the usual maintenance item on hot duty.
Can the pump handle liquid with solids?
No. It is intended for hot water and hot oil without solid content and with low corrosiveness.
What flow and head are available?
90 W gives 8 m head at 10 L per minute, 180 W gives 20 m at 30 L per minute, 370 W gives 35 m at 30 L per minute and 500 W gives 40 m at 30 L per minute.
What speed does it run at?
1400 or 2800 rpm depending on the build.

Above 80 degrees the usual assumptions stop working. Seal choice, expansion, venting and material all move at once, and the pump is only part of the answer.

Magnetic Drive Pumps Where A Leak Is Not An Option
Removing the shaft seal removes the most common leak path and the most common maintenance item. Here is where that trade is worth making and where it is not.
