What is the difference between API and ANSI pumps?

Choosing a Pump: ANSI or API? In general, ANSI pumps provide reliable service across a range of applications and are the pump of choice for chemical processing. They offer tremendous flexibility and ease of operation. API pumps are heavier duty and should be considered for higher pressure and temperature applications.

What is the latest API 610 edition?

Which pump is more efficient?

Where different pump designs could be used, the centrifugal pump is generally the most economical followed by rotary and reciprocating pumps. Although, positive displacement pumps are generally more efficient than centrifugal pumps, the benefit of higher efficiency tends to be offset by increased maintenance costs.

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 oh type pump?
