Pump skid anchorage without bolt hole 1

[JADEN98]

Hi Colleagues,

The client intends to install an injection pump skid weighing 3,000 lbs with a power rating of 15 HP on an existing foundation. The vendor has not provided any bolt holes for anchorage, stating that “in their experience,” the skid will not move as long as it is placed on a firm surface. However, since the skid components consist entirely of C4 channels, drilling holes directly into the outer flanges is not feasible nor practicable.

I am wondering if there is any standard detail available for anchoring such skids using clamp and wedge plate.

Thank you for your input.

That is a fairly small pump. I guess the question is how much experience does the vendor have? Their statement doesn't seem outrageous on the face of it.

I don't see why 4 clamps wouldn't hold it in place adequately enough.

Thank you for your response. Is there a reference for installation of these kind of pumps using clamps? Is it a standard practice?

I would just use 4 Kwik bolts with a oversized plate washer and sorta clamp it down. It then can be removed if need be easily without damage or drilling into skid.

The clamp arrangement I'd use would be a 12mm flat plate, 80mm wide by 140mm long with a square bar approximate equal to flange with welded on one end and a 18mm hole for a 16mm bolt ~1/3 of the way along the length.

Install the anchor and clamp next to the flanges such that the clamp pivots on the square bar and clamps the flange down.

I would draw a picture by it is a little difficult from my phone.

Do this.

Thank you so much for your clear instructions.

Would 4 HDA undercut anchors be a more conservative choice considering the vibration induced fatigue effects?

They are rather renowned in the industry (50 + years). Though if there will be any problem in future with this installation, nobody would remember that it was their recommendation we acted on.
