Description :
Internal gear pumps of the RH + series are a special design of gear pumps of the R series, designed for pumping various high-temperature fluids.
We can offer you gear pumps of the RH + series for pumping various liquids with a high temperature (up to + 300 °С).
Many processes of modern production occur by high temperatures, when it is necessary to move the fluid from one process cycle to another, preventing a drop in temperature. Petrochemical production, the production of vegetable oils, paints and plastic materials are just a few examples of such industries.
By solving such problems, the following conditions must be met:
- resistance of pump materials to high temperature
- design reliability
- low cost of operation and easy pump check
First of all, the safety of the maintenance personnel depends on the fulfillment of these conditions, as well as compliance with the technological conditions of production.
We can offer you a simple and reliable solution for such a task - a special design of gear pumps of the RH + series for high-temperature fluids and coolants.
A feature of this modification of the RH + series for pumping coolants is the materials of the pump, mechanical seal and design of the pump unit.
Performance materials are selected taking into account resistance to high temperatures and large temperature differences.
The thrust bearings of the shaft of the head gear (rotor) are made of bronze-nickel alloy, the shaft mechanical seal is made using pure graphite that is resistant to high temperature.
The pump is painted with heat-resistant paint that can withstand temperatures above + 400 °C.
High temperature gear pump options of RH + series:
- Different types of mechanical seal
- Heating casing
- Bypass valve, double bypass valve
We can also offer a complete unit with a drive, as well as the pump itself on a frame with a bare shaft.
