This is a specially configured unit. Grundfos does not publish a public datasheet, performance curve or dimensional drawing for this exact type key, so we do not list flow, head, motor rating, materials of construction or dimensions here rather than quote figures we cannot verify against the manufacturer. Non-standard CR builds sharing this connection code vary in head and base material, so construction is confirmed per order. Contact us with your duty point and we will confirm the certified curve and full specification with Grundfos before you order.
