High Temperature Pumps

Hot Oil Pump

Name: Hot Oil Pump
Brand: SEKO Pump Solution

A heat transfer pump with no axis seal: magnetic force carries the drive, so there is nothing to leak on a hot oil line.

Hot oil pump head coupled to a motor on a machine frame

Overview

What This Pump Does

The LP2251 heat transfer pump is built for high temperature duty to 350 degrees Celsius, lifting hot water and hot oil that contains no solids and is low in corrosiveness. The motor has no axis seal, with the magnetic force leading the drive.

Four builds cover the usual small circuit duties: 90 W at 8 m head and 10 L per minute, 180 W at 20 m and 30 L per minute, 370 W at 35 m and 30 L per minute, and 500 W at 40 m and 30 L per minute, running at 1400 or 2800 rpm.

Three-phase	230V±10%(220-240V
Single-phase	230V ±10% (220-240V)

Key Benefits

Why Hot Circuits Use This Pump

No Axis Seal

Magnetic force leads the drive, so there is no shaft seal to degrade at temperature and no leak path on a hot oil line.

Rated To 350 Degrees

The published rating for heat transfer duty, well beyond the limit of a standard water pump.

Four Sizes For Real Circuits

90 W to 500 W covers the pump sizes that thermal oil skids and heated tanks actually need.

Two Speeds

1400 or 2800 rpm lets the circuit be matched without throttling the line.

Application Scenarios

Where It Is Installed

Thermal Oil Circuits

Circulating heat transfer oil between heater and press, reactor or drying tunnel.

Plating And Developing Lines

Galvanisation, film and television developing, printing, spinning and weaving lines with hot liquid.

Process And Utility Heat

Petroleum, chemical, drug manufacture, environmental protection, food and water treatment duties listed on the data sheet.

Who It Is For

Thermal oil system builders
Plating and surface treatment lines
Print, textile and film processing plants
Process engineers replacing leaking hot circuit pumps

Problems It Solves

Hot oil destroys seals

There is no axis seal to destroy, which is the single biggest maintenance item removed from a hot circuit.

A leak on a hot line is dangerous

A closed pump head removes the leak path that makes unattended hot oil circuits risky.

Water pumps are out of range

Standard water pumps stop around 80 degrees. This line is built for heat transfer duty to 350 degrees.

Compared With Other Options

SKWS high temperature centrifugal pump	The SKWS handles far larger flows on pressurised water to 240 degrees. This pump is for small hot oil circuits with no seal at all.
Sealed hot oil pump	A sealed pump costs less but puts a wearing seal on a hot oil line, which is where most failures and leaks start.
