Vertical Turbine Pump Base Design
Vertical Turbine Pump Base Design
(OP)
We are replacing an existing old vertical turbine pump with a new one. Unfortunately, the new pump bolting dimensions (24" centre of bolt to centre of bolt,total of 4 bolts) are larger than the existing pump bolt dimensions (18" centre to centre).
The existing concrete pad is 22"x22"x24"high. Has anyone designed something similar, a steel pump base to mount on top of the concrete pad to accommodate the new pump bolt dimensions of 24" centre to centre? I was planning to design the 26"x26" steel base with HSS and 3/4" plate and make it quite heavy. The base would then be bolted to the concrete pad with the existing pump anchors(18" centres, 4 bolts). Is vibration an issue?
The pump is for a sump, 360 gpm at 19 ft TDH, 5 HP.
Thanks for any input in advance.

If you have vibration problems its not going to be caused by a long span of a skinny plate.

I wouldn't even think about using epoxy grout for anything less than 500 HP.

You could use an epoxy based paint on your skid and baseplate steel if you're pumping seawater. Maybe you should be using salt resisting concrete and epoxy coated reinforcement bars too.

Thanks for the advice..unfortunately I found them like that when I started working there..however some of the baseplates do need replacing so i will keep that in mind!
