Wanner's multi-diaphragm Hydra–Cell pumps can now be tested and certified according to API 675. Although all Hydra–Cell metering pumps are claimed to meet these performance standards, in terms of repeatability, linearity and steady state accuracy, Wanner has invested in a dedicated test facility that helps to verify performance of individual pumps.
API 675 is the specification for controlled volume, positive displacement pumps for use in service in the petroleum, chemical, and gas industries but is increasingly being adopted as the general industry specification for metering and dosing pumps.
The service is optional but is already reassuring users that Hydra-Cell P-Series metering pumps can meet or exceed their performance requirements. A more accurate knowledge of pump performance can often be a critical element in process optimization and the reduction of operating costs.
