Pump-Transfer Cooler Filtration Unit UKF

General

The UKF unit is a compact, easy-to-install system for offline filtration cooling circuits. It consists of a low-noise feed pump, a filter and a plate heat exchanger.

Product features

Continuous cooling and offline filtration extend the service life of the oil and of the hydraulic system. The offline unit ensures constant oil temperature – regardless of the cycle times of the hydraulic systems. Furthermore, consistent flow rates prevent pressure spikes in the heat exchanger.

Area of application

  • Plastic injection moulding machines
  • Pressing / Stamping
  • Machining centres
  • Hydraulic systems
  • Gears

Operating data

General

 

Ambient temperature +10 °C to +40 °C

Volumetric efficiency >90 % at ν = 40 mm²/s

Mounting position UKF-1: Optional, but easier to maintain if filter below pump

UKF-2 / UKF-3: vertical

Pump

Suction pressure across the suction connection max. -0.4 bar to 0.5 bar

Operating pressure (oil side) max. 6 bar

Medium (oil side) Mineral oil to DIN 51524 Part 1 and Part 2

Temperature range (oil side) +10 °C to +80 °C

Permissible contamination (oil side)

≤ NAS12 or ISO4406: 22/21/18

Max. viscosity see viscosity-temperature graph

Drive

Motor Three-phase electric motor

Insulation class: F

Protection class: IP55

Speed 1,500 / 1,800 1/min (50/60 Hz)
Heat exchanger

Heat exchanger connections: Female thread (max. tightening torque 160 Nm)

The pipes must be connected so that the connections are stress-free.

Linear expansion and vibrations from the pipes to the heat exchanger

must be avoided.

Medium (water side):

  • Water glycol (HFC)
  • Water
  • ll Oils

Temperature range (water side) +5 °C to +60 °C

Operating pressure (water side): max. 30 bar

Permissible contamination (water side)

The level of particles in suspension should be less than 10 mg/l.

Particle size <0.6 mm (spherical)

Thread-like particles cause a rapid increase in pressure losses.

Water quality The following ions are not corrosive under normal conditions: phosphate, nitrate, nitrite, manganese, sodium and potassium also see table on water quality
