FDF Series Liquid Ring Vacuum Pump (in close coupled design) are displacement pumps of uncomplicated and robust construction with the following
particular features :
nearly isothermal compression
oil-free, as no lubrication in the working chamber therefore non-polluting
capable of handling of nearly all gases and vapors
small quantities of entrained liquid can be handled
easy maintenance and reliable operation
low noise and nearly free form vibration
wide choice of materials, therefore applicable nearly everywhere
shaft not in contact with the medium
protection against cavitation as standard
incorporated dirt drain, no metallic contact of the rotating parts.
Pump body using native PP (listed companies) PVDF (import from French). Significantly improved the corrosion resistance and structure strength
Self-absortion cylinder and pump body be integrated together, so pump without welds, without leakage.
Middle cover is integrated adopt strong gluten solid.
High efficiency impeller design and an integrated, more improves the pump efficiency and long distance life.
Shaft seal material can choose different material with different environments.
The pump adopts high-quality virgin PP/PVDF to improve corrosion resistance corrosion resistance and structural strength
Super strong mid-sealing sealing structure design enhances the self-priming ability, no need for supporting bottom valve operation, and the suction lift height can reach 5 meters
The main body and the impeller are designed independently, which is convenient to disassemble and assemble
Built-in self-cooling anti-idling system, unique and innovative structure, idling time up to 2 hours
Features:
High pressure: the maximum pressure of standard configuration is 1.6MPa, special configuration can reach 3.5MPa.
Large displacement and lower speed.
The mechanical seal has stronger reliability and more flexible options: single face, single face with flushing, double faces with flushing.
Non-standard models have better versatility (abnormal interface, sealing scheme, rotor type, etc.).
The rotor locking nut has no distinction between positive and negative teeth, and there is no direction restriction on the inlet and outlet of the pump head.
