I had a recent assignment where we were looking at installing pumpable insulation into a casing due to hot spots. We were looking at Kaowool type HS pumpable. The product spec sheet recommends installation with an extrusion pump. Our vendor offers these pumps for rent, but they are currently all out for service at the moment. To get around this, I have been told you can use a hand pump instead, but I cannot seem to find any details or further information and our vendor does not offer the handpump as an option.
Has anyone ever used a hand pump for pumpable insulation before and if so can you direct me to a link of what sort of pump works?
This is mostly for information purposes because we are able to wait for the extrusion pump to become available. I have used pumpable before, but it was always with the extrusion type pump.
