Designed to API 675
Durameter pumps are built in accordance with API 675 specifications.
Designed to Adapt
At Durameter, we understand operating conditions are not always constant, so we designed the EV series metering
pumps for maximum flexibility and greater control. As requirements change, modification of the EV series pumps allow
for changes to plunger diameters, liquid end materials or converting to special designs when pumping slurries, viscous
or other challenging process fluids. For added convenience, the EV1 series pumps easily convert from a simplex to a
duplex configuration using the same pump frame or when connecting multiple frames to drive up to twelve heads using
a single motor.
Designed for Simplicity and Cost-effectiveness
The EV series pumps employ a revolutionary modular design with 4 independent assemblies, or cartridges, that are
independent and field convertible. This makes routine maintenance quick and easy, and increases your savings by
reducing downtime.
Designed to Assure Performance in Your Application
Durameter pumps are available with DURAmatic electronic stroke control for controlled processes. The DURAlert
diaphragm performance option is available to assure diaphragm integrity even in the most critical service. For added
assurance, all Durameter pumps are built in accordance with API 675 specifications.
