AP312HP Series Pump
External Gear Pump, Cast Iron, Single and Multiple, 40.0 – 75.0 Displacement cm³/rev.
The product range of SpA includes single pumps 05-100-212-212HP-250HP-300-312HP (corresponding with the common group denominations: 05-1-2-2.5-3) and several combinations of double pumps, triple pumps, and so on, that can be assembled together according to versions of displacement, flanging, and auxiliary valves.
Thanks to the positive field experiences recorded on the group 2 (AP212HP) and group 2.5 (AP250HP) cast iron pump and motor series, the product range is completed by introducing the new AP312HP cast iron pump group 3. The new pump has been developed with modern and robust design concepts.
Strong “2 pieces” structure, big shafts diameter as well as high-quality materials, allows to the AP312HP to reach the very high quality and performance levels, to fulfill the most innovative types of machines and applications.
