Air-cooled thermal oil pumps for high-temperature heat transfer

Thermal Oil Pump Manufacturer in Delhi NCR

Watershine air-cooled thermal oil pumps are designed to circulate synthetic and mineral thermal fluids at temperatures up to 350°C (660°F). The air-cooled design keeps the mechanical seal area separated from the hottest part of the pump, reducing the need for external seal cooling water in suitable applications. Watershine supplies thermal oil and thermic fluid circulation pumps from New Delhi for industrial heating applications across Delhi NCR and India.

Built for Zero Thermal Distortion & Leak-Free Hot Oil Circulation

Standard centrifugal pumps fail under extreme heat due to thermal expansion and rapid mechanical seal degradation. Our air-cooled thermic fluid pumps utilize an innovative heat-dissipating cooling barrier between the pump casing and the mechanical seal chamber.

By keeping the mechanical seal in a low-temperature zone using natural air convection, our pumps eliminate the complexity, maintenance, and utility costs associated with secondary water-cooling lines—ensuring long seal life and zero-leak reliability.

Why Use an Air-Cooled Thermal Oil Pump?

Air-Cooled Heat Shield Design:
Integrated thermal barrier wings dissipate heat naturally away from the seal and bearing assembly, keeping operational temperatures low without external fluid cooling.
High-Temperature Nodular Iron Castings:
Constructed from heavy-duty SS316, SS304, Nodular Cast Iron (JS 1025 / GGG-40.3) or Cast Steel to withstand continuous thermal cycles without cracking or warping.
Back Pull-Out Construction:
Allows maintenance teams to inspect, repair, or replace the rotating assembly and mechanical seal without disconnecting the pump casing from the suction and discharge piping.
Dual Bearing Protection & Safety Throttle:
Features liquid-lubricated silicon carbide sleeve bearings on the hot side and grease-lubricated ball bearings on the drive side, backed by an emergency safety stuffing box to prevent hazardous oil spurts in the event of primary seal failure.

Thermic Fluid Pump Selection Guide

Key selection parameters

Thermal oil pump selection should consider operating temperature, thermal-fluid viscosity at operating and start-up conditions, required flow and head, system pressure, pump speed and the properties of the selected heat-transfer fluid. Correct sizing helps maintain circulation while avoiding excessive mechanical and thermal stress.

Where thermal oil pumps are used

Air-cooled thermal oil pumps are commonly considered for industrial heating systems where hot oil or thermic fluid is circulated through heaters, heat exchangers and process equipment. Applications can include chemical plants, process heating, oil and gas systems, food processing and other thermal-fluid installations.

Thermal Oil Pump Maintenance

Protect pump reliability

Reliable hot-oil circulation depends on correct alignment, bearing condition, mechanical seal selection, lubrication and operating within the pump and fluid manufacturers’ limits. Regular inspection of vibration, leakage, bearing temperature and operating conditions can help identify problems before an unplanned shutdown.
