PB – DISPLACEMENT GEAR PUMP
For various products with different viscosities, flow rates and temperatures
Suitable for the supply, circulation, transfer, push, loading/unloading of products for the petrochemical, detergents, food and confectionery, chemical-pharmaceutical, polyurethane and polymer industries.
Particularly robust, it is ideal for use in all sectors where versatility, reliability and safety are required.
Executions according to applications using materials suitable for the fluids to be pumped (for body, covers, bushes, gaskets and seals).
The pumps of this family can be produced with cast iron (PB), stainless steel AISI 316 (PBX) or combined with carbon steel.
The pumps are available with or without built-in bypass valve. In the construction, particular attention is paid to heat treatments and sealing elements, in line with technological developments.
Special executions on request (see variations below).
Also available with special retrofittable magnetic drive coupling (MC).
