Large flow All-in-one Low-pressure coolant pump

This is a YTH corresponding to large flow & low pressure with cyclone filter. YTH-CI enables users to be free from troubles and filter maintenance around a coolant tank due to automatic clean-up unit by cyclone filter.

  • Total pump head 40~65 m
  • Maximum flow rate :
    • CI 15 x C 150 l /min
    • CI 30 x C 300 l /min
  • No suction filter is required (continuous operation only)
  • Applications to various types of coolant tanks

Plan-A Application to coolant tank + isolated clean tank

YTH-CI transfers filtered coolant from a coolant tank to an isolated clean tank. Filtered coolant is supplied to machining centers by High-Medium pressure coolant supply pumps. Chips and contaminants are pushed out from YTH-CI and collected by magnet separator or sedimentation tank.

Plan-B Application to integrated coolant tank and clean tank

YTH-CI can totally clean up a coolant tank by circulation flow. At the same time, YTH-CI also automatically backwash plate strainers between a coolant tank and a clean tank by suction of dirty coolant, which reduces maintenance work for backwash plate dramatically.

Plan-C Application to single coolant tank (without clean tank)

YTH-CI supplies filtered coolant to nozzles in a machinery tool. When the machinery tool stops metal cutting operation, YTH-CI automatically switches to cleaning of a coolant tank by circulation flow.

YTH-CI – the All in one coolant unit

  • Coolant supply Filtered coolant is supplied to avoid clogging and damages to surface of work piece
  • Chips and contaminants collection Chips and contaminants in a coolant tank is automatically collected to reduce maintenance work dramatically
  • Agitation of coolant Making circulation flow in a coolant tank delays fermentation of coolant, which results in less odor around the coolant tank

Unique reversed cyclone system enables to separate clean coolant and contaminants. Contaminants are pushed up through side surface of cyclone filter by centrifugal force and discharged. Clean coolant are collected to center of cyclone filter and boosted up by multiple-stage impellor pump.

Impeller Pump

  • Multiple-stage impellers are used for YTH-CI to boost up and supply a large quantity of coolant
  • Compatible types of fluid
  • Water-soluble coolant fluid
  • Not for Water-insoluble coolant fluid, lubricant oil or fuel oil
  • Not for clear water, purified water, aqueous solutions and viscous fluids without rust-preventive property, corrosive liquid, solvents, and oils
