MAXUM OH1

Maxum OH1

Heavy-Duty, Horizontal End-Suction Pump

Our heavy-duty, horizontal end-suction pump for handling hydrocarbons and process industry applications, includes flows up to 11,000 GPM.

Our heavy-duty Pump

Designed as a foot-mounted version of our API centerline-mounted Maxum OH2, the Maxum OH1 is an industry workhorse. The Maxum OH1 can be motor, engine, or turbine-driven and is ideal for water, hydrocarbons, caustic and acid applications. With hydraulic performance to 11,000 GPM and 720 feet of head, this pump family is available in carbon steel, 12% chrome, 316L and duplex stainless steel, according to standard API material codes. In addition to these, higher alloys such as Alloy 20, Hastelloy B or C, Monel and titanium are also available.

As standard these units come with oil-lubricated bearings with labyrinth isolators, and connections for temperature probes. Common options include various cartridge seals and API piping systems. Flanged or NPT auxiliary connections, cooling jackets, spacer couplings, and various levels of performance testing are also available, depending on users' requirements. Available heavy-duty baseplates result in maximum flange loadings that meet or exceed the requirements of API 610. With some of the most efficient hydraulics in the industry, the Maxum series offers reliability, low lifetime cost, and lasting value that has made Carver one of the most trusted names in pumps.

FEATURES

1. Connections: Class 300 ANSI flanges with centerline discharge assist in self-venting.

2. Wear Rings: Replaceable casing and backhead wear rings maintain efficiency and balanced axial loads.

3. Casing: Back pull-out design with registered fits and fully confined gaskets assure sealing and alignment of critical fits. Casing drains included as standard. Centerline mount options available in OH2 configuration.

4. Impellers: Enclosed, high-efficiency impellers balanced to ISO 1940, Grade G2.5 for vibration-free operation. All impellers are keyed to shaft.

5. API 610 Seal Chamber: Provides an ideal seal environment for both single/dual, pressurized/unpressurized cartridge mechanical seals. A full range of piping plans is also available to maximize seal life.

6. Bearing Frame: Heavy-duty bearing housing with cooling fins, fan and labyrinth seals keep oil clean and cool for greater bearing life.

7. Bearing Lubrication: Oil-lubricated bearings with standard flooded or optional flinger lubrication. Conversion to purge oil mist or pure oil mist is possible without additional machining.

8. Cooling Fan: Cooling fan allows ambient temperatures to 110° F and fluid temperatures to 300° F. The cooling fan also extends bearing life.

9. Shafts: Minimal shaft deflection extends mechnical seal and wear ring life.

MAXUM OH2

Maxum OH1

API 610 Compliant End-Suction Pump

Our heavy-duty, horizontal end-suction pump for handling hydrocarbons and process industry applications, includes flows up to 11,000 GPM.

API Maxum OH2

The API Maxum OH2 is designed for optimum reliability, featuring rugged construction and state-of-the-art mechanical design. Units are well suited for applications that include petroleum refining/production/distribution, petrochemical/chemical processing, boiler circulation/high- temperature applications, and general industrial use. A workhorse in the industry, these pumps are designed for years of service, in some of the toughest environments imaginable.

This model is fully compliant with latest edition API 610 specifications. Standard features include renewable casing wear rings, API 610 seal chamber sized to accommodate 682 mechanical seals, back pull-out construction, dynamically-balanced impellers, heavy-duty carbon steel/finned bearing housing equipped with labyrinth-type oil seals, and fan cooling. Locations are also included for temperature probes, as standard. Common options include single, double or tandem mechanical seals, and various seal flush systems. Heavy-duty baseplates, casing jackets, and various levels of performance testing are also available.

Together, these features combine to produce some of the most efficient hydraulics in the industry and shaft deflection values meeting or exceeding those of API 610 requirements. The API Maxum OH2 is also available as an OH1 design for lower temperature applications.
