HZC (OH2 API 610 pump) - Rodelta

Rodelta HZC (OH2 API 610 pump)

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. Satisfying this standard, the HZC meets the high level performance requested by refineries and petrochemical industries.

Rodelta HZC (OH2 API 610 pump)

Features: HZC (OH2 centerline mounted)

• 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, 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 verylow vibration levels during operation

Specifications:

• Delivery size up to 300 mm
• Capacity 10m3/hr to 1920m3/hr
• Head up to 380m
• 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

Applications:

• Fluid handling in oil refineries and petrochemical industry
• High temperature and high pressure critical applications in chemical and allied industry
• Upstream, pressure booster
• Midstream, process transfer, bottom reflux, propane/butane/LPG handling, diesel oil/gasoline/naphtha/lube oils etc., sodium carbonate/caustic sour water, MEA/DEA/TEA,
• Fertilizer, carbamates/lean and semi lean solutions, NH3 feed, other removals
• Power plant, Hot water circulation, condensate transfer, fuel oil
• Onshore/Offshore installations
• FSPO platforms
• Hydrocarbon storage (H2)
• Liquid gas plants (LNG)

Constructional features:

• The HZC complies with the 12th edition of API 610 without any exceptions.
• Suction and discharge flanges are available drilled to either ANSI or DIN-EN standards, flange rating comply with API 610 nozzle load requirements.
• The pump casing, cover and seal cover incorporate a fully confined gasket.
• Mechanical Seals conform to API 682 / ISO21049 and are fitted into the API compliant seal chamber, either single, double or engineered seals can be accommodated including advanced gas barrier seal technology, that meet the full process requirements. All seals are provided with the relevant API compliant flushing, cooling, heating, quench and buffer fluid systems and associated pipework.
• Heavy duty axial and radial bearings support the pump shaft. Located within the cast steel housing are labyrinth type radial oil seals
• Oil lubrication with oil bath or oil flinger to splash the oil
• Oil level monitoring of the pump by constant level oiler
• Bearing housing with bearing covers having replaceable labyrinth type end seals
• Mounting pads on Rodelta baseplate design to create tension free machined baseplate.
• The interchangeability of parts also from different Rodelta pump designs resulted in fewer parts in stock

Optional: Water-cooled bearing houses, pure mist or purge mist lubricated bearing houses
