Hot oil circulating pump for thermal fluids heating system

Robust horizontal, single-stage centrifugal pump engineered for circulating hot thermal fluids in closed-loop heating systems. The cantilever, single-suction design uses axial inlet and vertical-up discharge and is mounted together with the drive motor on a common baseplate for compact, inline installation.

Key features

• Horizontal, single-stage single-suction cantilever construction for reliable circulation of heat transfer oils and other thermal fluids
• Axial (inlet) and vertical-up (outlet) orientation for straightforward piping arrangements
• Baseplate-mounted with motor for ease of alignment and compact footprint
• Double-end ball-bearing support: front end lubricated with oil, rear end lubricated with grease for extended bearing life
• Seal arrangement combines high-temperature packing and a hard-alloy mechanical seal to maintain reliable sealing at elevated temperatures; PTFE lip seal provided
• Central guide pipe to observe and recover sealing/thermal oil
• Air-cooled design for natural heat dissipation without auxiliary cooling

Materials and operating limits

• Pump wet-end materials: cast iron or stainless steel options to suit fluid compatibility and corrosion resistance requirements
• Designed for clean liquids (no solid particles)
• Rated for hot fluids up to 350 °C (suitable for hot oil and other high-temperature heat-transfer media)

Applications

Widely used for circulating thermal fluids in industrial hot oil heating systems, including:

• Petroleum and petrochemical processes
• Chemical processing
• Rubber and plastics industries
• Pharmaceutical manufacturing
• Textile and dyeing operations
• Road construction (asphalt/heating systems)
• Food processing (where high-temperature heat-transfer fluids are used)
• General machinery and industrial heating systems

Installation & maintenance notes

• Install on a rigid, level baseplate together with the motor to preserve shaft alignment and minimize vibration
• Suitable only for liquids without solid particulates; upstream filtration recommended where contamination is possible
• Regularly check seal condition and the guide pipe for seal recovery; maintain recommended lubrication intervals for front and rear bearings
• For service life at the upper temperature range, select stainless-steel wet-end materials and ensure compatible sealing materials and backup cooling where needed

Options and customization

• Material selection (cast iron, stainless steel) and mechanical seal materials can be specified to match fluid chemistry and operating temperature
• Available in multiple sizes and performance ranges; motor and coupling options can be supplied to meet site-specific power and speed requirements

For procurement and engineering inquiries, confirm pump size, flow/head requirements, operating temperature, and fluid chemistry so the correct material and seal configuration can be selected.
