HF
The HF series are non-self priming, horizontal, single-stage, centrifugal pumps with
cast iron pump bodies and brass impellers. They have 416 stainless steel shafts, fi tted
with carbon ceramic and NBR mechanical seals and have A.C., TEFV, IP44 motors,
but neither power leads nor switches are supplied. Single phase motors incorporate
an overload protection device. The design of the volutes and impellers, with large
■ 1½" (40mm) – ✔ Circulating
passages, make them suitable for pumping dirty water. They are capable of pumping
2" (50mm) inlet ✔ Transfer
medium to large volumes of water, which makes them particularly good for irrigation
■ 0.37kW – 2.2kW ✔ Irrigation and processing applications. A broad choice of sizes enables cost effective pump
selection. Suitable for water temperatures up to a maximum of 90ºC. They should not
