The six-roller Diamond Series 6600 roller pumps offer 19.6-gpm maximum flow output at 1,000 rpm and handle fluid temperatures to 140°F. Standard roller rotation is clockwise with counterclockwise available. The pumps are designed with a special alloy body and end plate for maximum durability, especially when used in harsh environments. To minimize seal wear, shafts are made of 416 stainless steel with an extra-fine finish. Both ends of the shafts are supported with heavyduty sealed bearings, and a Buna-N seal ring provides a positive seal between the end plate and pump body.
