YTH-ES– Medium Pressure Unit for Through-spindle Coolant System –

Trochoid™ Type
Medium Pressure Unit

Turbulence™ Filter

Special turbulence cleans the filter automatically, rendering the filter clog free.

Trochoid™ pump/2.0 MPa, 1.5 MPa

A rotor turning in a trochoidal curve generates pressure to suck and discharge fluid. This is an extremely efficient self-priming pump.

TAZUNA reduces the electric power cost further by approximately 20%. 
The pressure and flow rate are automatically adjusted.

FEATURES
YTH-ES

An All-in-one, Medium Pressure Coolant Unit

All components of a coolant system are consolidated into a single pump. No inline and suction filters are required. The saved space expands the available plant space, resulting in a higher production efficiency.

  • Maximum operating pressure: 2.0 MPa.
  • Maximum flow rate: 28.8 liters/min.
  • No suction filter is required.
  • No inline filter is required.
  • No plumbing is required to interconnect various components.

Turbulence™ Filter

Our special Turbulence™ design generates turbulence around the surface of the filter with 2 wing-shaped vanes rotating around the filter and can wash away sludge from the filter surface continuously.

High Efficiency Trochoid™ Pump

  • Compatible fluid type
    • Water soluble coolant, non-water soluble coolant.
    • Incompatible with lubricant oils, fuel oils.
    • Incompatible with clear water, demineralized water, aqueous solutions and viscous fluids without rust-preventive property, corrosive fluids, solvents, oil-based materials.
  • Relief valve is built into the pump.

YTH-ES Type (Wear-resistant Model)

For its special wear resistant structure, YTH-ES can be installed on coolant tanks of machines that generate hard and abrasive swarf.

  • Balance Plate
    • Pump generates inner pressure to press the balance plate toward the Trochoid rotor side, which helps in reducing the clearance created by wear on rotor side and thereby minimize the pressure drop, ensuring desired performance for a longer time.
  • Shaft and Bearing Reinforcement
    • Improved wear resistance by employing sprayed ceramic on shaft bearing area and use of ceramic bearing.
  • Double Seal & Cartridge System
    • Seal area is reinforced to prevent leakage and cartridge system ensures ease of replacement.

YTH-ES LINE TYPE

*The model number of Line type ends with capital letter “L.” The pump specification is the same as YTH-ES.

NOP Filter Pump External Type

Unlike normal type that can only be installed upon a coolant tank, this external type can be installed independently in a distant place with an extension pipe. 
Alteration of tank cover is no longer necessary, allowing quick and easy retrofitting.
