The pump type HZC ( OH2 ) is a series of horizontal overhung centerline mounted, single stage, single suction heavy duty centrifugal pumps with diffuser and volute design casings. The design of HZC complies with the latest edition of the American Petroleum Institute standard ‘Centrifugal Pumps For General Refinery Services’, also known as API 610/ ISO13709.

• Delivery size up to 300 mm

• Suitable for liquid Temperature: Up to 425ºC
• Sealing Arrangement: mechanical seals (dual- and gas seals are possible)
• Flange rating: CI. 150/300/600
• API material options available  NACE
• ATEX approvals available on request

• Single stage overhung design pump – API610 (OH2).
• Heavy duty, centerline mounted, radially split casing.
• Back-pull out unit design. Pump internals can be taken out without disconnecting suction/delivery piping or moving driver.
• Due to the centerline discharge the casing is self-venting.
• The impeller is a closed radial design, dynamically balanced and incorporates a wear ring on either side of the impeller. (The HZC can also be supplied with a semi-open impeller for liquids which are sensitive to clogging.)
• Diffuser benefits,(designed diffuser technique) reduces radial loads, reduces minimum flow requirements, high efficiency at any duty.
• The HZC can be equipped with a self-priming kit that makes the pump self-priming.
• For larger volumes, volutes are used and fitted with double tongues to reduce radial loads.
• The design of the pump ensures very low vibration levels during operation.
