Summary
RY Series Air Cooled Centrifugal Hot Oil Pump is a heat transfer oil pump designed to handle heat transfer oils at temperatures up to 350°C. The RY series hot oil pump is a centrifugal, single-stage, horizontal shaft type. The impeller features a rear impeller blade self-balancing design. No cooling of the seal chamber is required. Typically, the pump is driven by an electric motor, which is connected to the pump via a flexible coupling. A flexible spacer coupling can be installed, allowing the entire pump support to be disassembled without removing the pump casing and motor from the baseplate. The coupling is protected by a cover to prevent external intrusion.
Scope of Application
Cast Steel Material: Suitable for conveying high-temperature media without metal solid particles, with temperatures ranging from 20°C to 350°C.
Stainless Steel Material: Suitable for conveying high-temperature chemical media or food fluid media without solid metal particles, with temperatures ranging from 20°C to 350°C.
Applications
Synthetic Fiber Industry: Polymer melting, spinning, stretching, etc.
Textile and Dyeing Industry: Heat setting, drying, heat-melt dyeing, etc.
Plastics and Rubber Industry: Hot pressing, calendering, extrusion, vulcanization molding, etc.
Paper Industry: Pulp processing, corrugated paper production, etc.
Timber Industry: Plywood, fiber hot pressing, wood drying, etc.
Construction Industry: Asphalt heating, etc.
Petroleum and Chemical Industry: Polymerization, condensation, distillation, fractionation, melting, etc.
Oil and Fat Industry: Fatty acid distillation, fat decomposition, esterification, etc.
Structural Features
- Casing Part: Consists of the pump body and pump cover.
- Rotor Part: Comprises the impeller, shaft, and impeller nut.
- Bearing Part: Equipped with two bearings inside, serving as the rotor’s support structure.
- Transmission Part: The pump is connected to the prime mover via a claw-type flexible coupling. The prime mover can be a standard motor or an explosion-proof motor, and the pump rotates clockwise when viewed from the coupling end.
This pump features a redesigned structure compared to traditional hot oil pumps, adopting a natural heat dissipation cooling method. This reduces the pump’s size, simplifies the structure, lowers operating costs, and ensures safety and reliability.
