Best answer: What is the difference between ANSI and API?

In general, ANSI pumps provide reliable service across a range of applications and are the pump of choice for chemical processing. … API pumps are heavier duty and should be considered for higher pressure and temperature applications. They are the pump of choice for aggressive oil refinery processes.

What does API stand for in pumps?

API Pump Standard – Defined

American Petroleum Institute (API) is the largest U.S. trade association for the oil and natural gas industries. API focuses on developing petroleum and petrochemical equipment and operating standards.

What is difference between OH & BB pump?

OH – Overhung pumps – The impellers of these pumps protrude from the bearings. … BB – Between bearing pumps – The impellers of BB pumps are suspended in between the supports. For all pumps of this type, the impeller is placed horizontally, in plane with the bearings.

What is API and non API pumps?

In general, ANSI pumps provide reliable service across a range of applications and are the pump of choice for chemical processing. … API pumps are heavier duty and should be considered for higher pressure and temperature applications. They are the pump of choice for aggressive oil refinery processes.

What does API 610 mean?

API 610 is the API standard relating specifically to centrifugal pumps and centrifugal pumping systems. It provides design criteria for the design of the actual centrifugal pump, as well as how the centrifugal pump is to be tested, and what type of base it is to be mounted on.

What is non API pumps?

Non-API (American Petroleum Institute) certified pumps are less resistant to heat and pressure; however, they provide flexibility of interchangeability of pumps from one manufacturer to another. ∎ Non-API liquid pumps are built with OEM pumps and motors.

What is special about ANSI pumps?

ANSI pumps offer plant operators the possibility to switch pumps and brands without having to change or redesign motor attachment, piping, coupling or baseplate dimensions. Other benefits include: Dimensional interchangeability across manufacturers and brands. … Less expensive than API pumps.

What are BB2 pumps?

The BB2, type KBSD is a between bearing pump, single stage, double suction impeller pump conforming to API 610. The casing is center line mounted and with case wear ring.

What is between bearing pump?

A between bearings centrifugal pump uses one or several impellers installed on a shaft that is suspended at both ends between two bearings. An overhung centrifugal pump uses one impeller installed on a shaft that is suspended at one end by bearings.

What is centerline mounted pump?

Most ANSI pumps are designed with foot mounted casings. … Centerline support simply means that the pump casing is supported at the shaft centerline. This allows thermal expansion growth of the casing to be symmetric from the shaft centerline outwards.

What is api676?

API 676 is the API standard for rotary, positive displacement pumps. The standard provides design criteria for all types of rotary PD pumps.

What is VS type pump?

VS1 type pump is a single casing vertically suspended type design. It is used as a wet pit or diffuser pump. The column of a pump is used as a discharge from the pump.

What is a BB3 pump?

General. Our API 610 type BB3 pumps are multistage, centre line mounted, axial split, single suction, between bearing pumps. The pump and motor are flexibly coupled and installed on a common baseplate.

What is an OH1 pump?

General. Our basic API 610 type OH1 pumps are foot mounted, single stage, overhung pumps with a single bearing housing. The pump and motor are flexibly coupled and installed on a common baseplate. The coupling design allow removal of the back pull-out assembly without disturbing the driver, coupling hubs or casing.
