Product overview
Selected around the complete duty.
API 675 is widely specified for controlled-volume positive-displacement pumps used in critical process services. Petrox coordinates the duty review, VK pump selection, documentation and commercial supply for applicable projects.
Available solutions include plunger and hydraulically actuated diaphragm designs with adjustable capacity, multi-head arrangements, accessories and packaged dosing systems.

Frequently asked questions
Practical answers before selection.
Does every dosing pump comply with API 675?
No. Compliance depends on the pump design, selected configuration and the specific project requirements. Petrox reviews the specification before selection.
What duty data is required?
At minimum, provide fluid details, normal and rated flow, suction pressure, discharge pressure, temperature, viscosity and required materials.
Can Petrox coordinate project documentation?
Yes. Petrox coordinates technical submittals, approved data sheets, inspection requirements and commercial communication with VK Pumps.
