RY thermal oil centrifugal pump

High-temperature, water-free centrifugal hot oil/thermal oil circulation pump engineered for continuous circulation of weakly corrosive, particle-free heat transfer fluids at service temperatures up to 350°C.

Key features

• Single-stage, single-suction cantilever (foot-supported) design with axial suction and vertically upward central outlet; pump and motor are mounted together on a baseplate for compact, aligned installation.
• Robust double-end ball bearing support: front bearing lubricated with oil, rear bearing lubricated with grease. A central guide pipe allows visual inspection of seal condition and recovery of heat transfer oil.
• Natural (air) heat dissipation — replaces traditional water-cooling to simplify structure, reduce footprint and lower operating and maintenance costs.
• Hybrid sealing system: combination of packing seal and mechanical seal. Packing material is specified for thermal adaptability; the mechanical seal uses cemented carbide components for improved high-temperature performance.
• Advanced lip seal using third‑generation PTFE for superior sealing durability and heat resistance (reported significantly higher performance versus conventional rubber lip seals).

Model breakdown (example: WRY 100-65-230)

• WRY: water-free (no water cooling) hot oil pump
• 100: inlet diameter 100 mm
• 65: outlet diameter 65 mm
• 230: impeller nominal diameter 230 mm

Typical applications

Used widely in industrial hot oil circulation and heat-transfer systems across sectors including petroleum, rubber, resin, textile, printing, building materials, road construction and general machinery — suitable for circulating thermal oils and other weakly corrosive, high-temperature, particle-free liquids.

Ordering and specification checklist (provide these when requesting quotes)

• Model number and required flow / head (Q / H)
• Maximum fluid temperature and fluid properties (viscosity, density, corrosiveness)
• Inlet and outlet flange sizes and orientations
• Required mechanical seal / packing materials or special seal arrangements
• Motor coupling and power / speed requirements
• Any special material or surface requirements for wetted parts

Benefits

Compact, serviceable design optimized for high-temperature heat transfer fluids; lower operating cost and maintenance complexity compared with water-cooled alternatives; improved sealing performance for reliable long-term operation in thermal oil systems.
