[RE-wrenches] Lorentz Sub Pump

[David Katz]

Hi Jeff O,
What do you use for power for the relay coil?.  The pump can run on 
voltage up to 300 VDC. I suppose you could tap the output of one module 
or add a separate small module.

For your need you have at least 2 sweet options - 1) get a relay to switch the pump power and use a float switch to control the coil, go with a SSR for even higher reliability.  This is a $50 substitute for a $300 CU-200. 2) Use a Cla-val at the tank and a pressure switch and 2gal press. tank at the pump. This works at any distance w/o control wires and is fully hydraulic and highly reliable plus this valve does not throttle as it reaches full. This is my control of choice if the distance between pump and tank is much over 400', cost must be considered as this is about a $700 setup.
