YTH-CT/CS– Medium Pressure Unit for Through-spindle Coolant System –

Trochoid™ Type
Medium Pressure Unit

Double-cyclone filter

Two layers of double cyclones (one large cyclone and six small cyclones) remove sludge from the coolant fluid.

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.

FEATURES
YTH-CT/CS

All-in-one Medium-pressure
Coolant Pump

All components of a coolant system are consolidated into a single pump. 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 plumbing is required to interconnect various components.

Double-cyclone Filter

A proprietary double-cyclone system removes sludge.The first cyclone removes larger debris, while the second cyclones remove smaller particles. The inline filter cleaning cycle is extended by 24 times.*Sludge larger than 20 μm can be removed. (When using water-soluble coolant fluid.)

YTH-CT/CS Double Cyclone

High Efficiency Trochoid™ Pump

CT employs a Trochoid™ pump which excels in fluid control efficiency. The double-cyclone system sorts out sludge and enables direct connection to the coolant tank.

  • Compatible fluid type
    • Water soluble coolant.
    • Incompatible with non-water soluble coolant, 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-CS Type (Wear-resistant Model)

For its special wear resistant structure, YTH-CS can be installed on coolant tanks of machines that generate hard and abrasive swarf that YTH-CT cannot handle.

  • 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.

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

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.
