Pump Units
PU-1	○	Pump Unit complete with ESD protected reservoir, decoupled base plate and temperature sensor for speed control purposes, speed / power adjustable by voltage (7-12 V / 4-20 W), maximum flow rate 3l / min with Galden HT 135 @ 25°C, 120 x 88 x 94 mm³
PU-2	●	Available from February 2012: "Intelligent" pump unit with coolant reservoir and built-in control electronics for the pump motor and possible external radiator fans. Highly reliable design for professional purposes. The pump housing / reservoir is milled from a massive aluminum block and allows an absolute leakage free operation also at high temperature and high pressure. The front side of the unit, which is usually mounted behind the frontpanel of a system housing (e.g. a 19 inch housing unit), has an o-ring sealed viewing window for the built-in flow turbine wheel. The flow turbine wheel serves as a visual flow indicator and as digital flow sensor in the same time. Double ball bearing in connection with optical scanning guarrantees a MTBF of several hundred thousand hours for this safety relevant part component. The built-in electronics is monitoring the coolant flow, the tank fill level (also by optical sensors), the coolant temperature, the motor function and the supply voltage. The speed of the pump motor and the speed of the externally connected radiator fans is regulated proportionally to the coolant temperature. The automatic speed control can be turned-off by a logic signal for full cooling power or external speed control over the supply voltage, if demanded. In case of any fault condition (over temperatrue, flow disturbance, empty reservoir, missing or incorrect supply voltage etc.) a relay contact is immediately released to protect the connected power electronics in the cooling circle. For Behlke HTS high voltage switches, the alarm contact (normaly closed contact) will simply be connected between the "Inhibit" and the "GND" input of the switch control. Any false or crititical operating condition will also be indicated by different color illuminations of the coolant, which is visible trough the viewing window. During normal cooling operation the color of illumination is blue. Other colors are available, to meet individual front panel design requirements. If ordered with option "IHE" (internal heat exchanger), the pump block with its plain milled surfaces can also be utilzed as a highly efficient heat exchanger / heat sink. With the help of the option "IHE", the coolant heat can be easely transferred via the housing block to an existing heatsink. This can be a classical heatsink or any large massive metal housing (e.g. a 19 inch housing with thick front panel) or a large metal chassis of a machine. A cooling solution with option "IHE" allows a power dissipation of at least 500 Watt without active radiators. The maximum cooling capacity with sufficint active radiators is approx. 3000 Watt for the standard pump unit and approx. 5000 Watt in connection with the power option "30W". The option "EFSI" (extra features for system integration) includes an additional optocoupler output (open collector), a digital flow signal output and an integrated coolant temperature sensor according to customers specifications (PT100, KTY, NTC etc.) PU-2 Features: - Non-blocking, highly reliable pump motor for industrial purposes with coolant lubricated and self-adjusting ceramic bearing - Guarranteed motor life expectancy >50,000 hours (typical 100,000 hours) at maximum temperature / maximum load - Temperature depending speed control (can be switched off) for low power consumption and maximum motor life expectancy - Maximum flow rate > 3l / min with Galden HT-135 @ 25°C and < 30 cm height difference.

Safety shutdown / alarm at T>65°C (149°F) - Alarm output by a passive (normaly closed) relay contact and by an additional opto coupler with open collector (option EFSI only) - Fill port and overpressure valve (0.5 bar / 7 psi) on top lid. Alternatively on frontside over the viewing window, if installed in 19" housings. - Useful reservoire volume approx. 400 ml (13.5 oz), air buffer volume (volume change compensation) approx. 100 ml (3.4 oz) - Threated inserts, metric, d = 5 mm (M5) on bottom, right side, rear side and front side for heatsink attachment (8 threaded inserts on each side). Alternative attachment by a flange plate. Flange and sufficient M5 screws are included in supply. The plastic spacer on front side can be removed, if the viewing window shall be in line with a front panel plate. Please ask for a modified window thickness, if your front plate has an unusal thickness. - Housing massive aluminum, black anodized, block dimension (without spacer and removeable flange) 120 x 100 x 100 mm³ (HxWxD), net weight without coolant 1.95 kg (4.3 lb)

Option 30W		Increased pump power (12-30 W). Recommended for systems with > 2000 Watt power dissipation. Maximum flow rate > 5l / min with Galden HT-135 @ 25°C. For 12 VDC. Please note the higher current consumption of approx. 2.5 A. Dimensions and weight as above.
Option IHE		Internal heat exchanger for the heat transfer via the plain milled pump block surfaces. The reservoir volume is reduced by approx. 10%.
Option H-CF		Housing block with cooling fins for secondary air cooling. Recommended In connection with option IHE. Cooling fins can be attached on the rear side and / or the right side of the housing block. Heat resistance down to 0.2 K/W per side (forced air convection, air velocity >4 m/s).
