Product Description

Being a client-driven organization, we are offering a world-class assortment of Nop Make Trochoid Pumps to clients. The maxim operating pressure of the pump is 2.0MPa while 28.8 liters per minute is the maximum flow rate. The flow & pressure rate are automatically adjusted. Apart from this, these pumps save electricity bill due to their high energy efficiency features. These pumps are competed with copper winding, steel blades and other basic electric components that ensure longer working life, constant performance and cost effectiveness. We offer these Nop Make Trochoid Pumps at cost-effective prices in market.

Salient Features :

  • Pump: Trochoid
  • Motor: 750~1500 W/AC
  • Flow rate: 12~28.8 /min
  • Maximum Pressure: 2.0 MPa

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.

Compatible with the TAZUNA fluid control system (software)

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

An All-in-one, Medium Pressure Coolant Pump

All components of a coolant system are consolidated into a single YTH unit. No line and suction filters are required. The use of YTH-ET reduces the required space to about 1/20th by volume of that occupied by a conventional coolant system. 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 line filter is required
  • No suction filter is required
  • No clean tank is required
  • No transfer pump is required on the coolant tank end
  • No plumbing is required to interconnect various components

Automatic Self-cleaning Turbulence Filter

Our special Turbulence design generates turbulence. The combined action of the turbulence and centrifugal force washes away chips from the filter automatically. The result is a maintenance-free unit with a stable high pressure and large flow rate.

Chips larger than 20m in size is removed (when using water-soluble coolant fluid).

High efficiency Trochoid pump

  • Compatible types of fluid
  • Water-soluble coolant fluid
  • Water-insoluble coolant fluid of 15 mm2/s or less viscosity
  • Not for 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
  • Relief valve is built into the unit

S type (Wear resistance)

  • For its special wear resistant structure, S type can be installed on coolant tanks of machines which are machining materials which generate hard and abrasive Chips.
  • Balance plate
  • Pump generates inner pressure to press the balance plate toward the Trochoid rotor side, which helps in reducing the clearance created due to wear 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 usage of ceramic bearing.

Double seal & cartridge system

  • Seal Area is reinforced to prevent leakage and Cartridge System ensures ease of replacement

Huge Energy Saving Effect Reduces Utility Costs

  • The use of YTH-ET results in huge energy savings over the conventional centrifugal pumps. The electric power cost is greatly reduced.
  • Operating cycle: total 80 seconds cycle
  • Unload (0MPa) 20 sec. Coolant through (1.1 MPa) 20 sec.
  • Unload (0MPa) 20 sec. Coolant through (1.1 MPa) 20 sec.
  • The calculation is based on operation 8hours/day,
  • 365days/year, and the electric power billed at 20/kWh.
  • Results may differ according to the conventional pump specifications and the machining conditions reference data
