  • Plastic Injection machine pump start up question

    I have a Van Dorn 75 and we are getting around to starting it up. In the manual it says to refer to the pump for direction of rotation. The only arrow I can find is this one. Witch looks like clock wise from the drive shaft side of the pump. Just want to double check my assumption. I have more questions but will work my way threw them one at a time.

    If in doubt - Make sure the oil is at the proper level and bump then over, one at a time and look for pressure at the output. Way we always bumped them was at the starter relay. May have to crack a line to see the leak from the slight pressure. Also good to do in case someone messed with one motor and its the one that's backwards...
