API 675

API 675 double diaphragm pumps

Our API 675 double diaphragm pumps are a cost-effective solution for our customers’ low flow rate or low pressure injection applications. The benefits of an API 675 diaphragm pump in low flow/pressure applications include easy flow control through manual/electric stroke adjustment.

Typical API 675 Applications

Typical process pumping applications include scale and corrosion inhibitor injection, biocide, oxy scavenger, and many other chemical injection operations. However, if you require higher flow/pressure pump skid packages, then visit our API 674 page.

Technical Overview

Our API 675 double diaphragm pump units are generally air motor, electric motor, or hydraulically driven. We design and manufacture for all hazardous area operating environments including ATEX Zone I and Zone 2, NORSOK, CSA and CRN.

These controlled-volume pumps feature an adjustable stroke which is controlled in line with injection requirements. The equipment is generally skid or crash frame mounted. Crash frames are popular as they offer a good balance of protection for the equipment, low unit weight, and good access to components. Whereas pump skids offer maximum weight saving and all-round access to the components.
