that make them ideal for water processing,
as well as oil, fuel or antifreeze
transfer. The pumps also work
well with seawater, acids and alkaline
solutions. There are six models in
the series, all with different flow and
pressure capabilities. The pumps are
available with nickel-plated bronze
or polytetrafluoroethylene (PTFE)
gears, and stainless-steel or brass
pump bodies. - Clark Solutions Inc.,

exchanger and precision temperature
controller that can be fitted into process-control
circuits without adding
volume. MicroPulse delivers up to 1.75
mL of gas at standard temperature
and pressure. Advantages of the device
include: no moving parts, no need
for compressed-air source, and the application
to which it is connected can
initiate a flow pulse automatically at
any interval. - Intertech Development

These pumps are ideal for oil,
fuel, water and acid transfer
The UP Series of self-priming gear
pumps is available in configurations
Additional control options
for these valves
Spira-Trol control valves have extended
options to ensure that the
valves can be optimized for a specific
customer application. Pneumaticpiston
actuators have been added to
the diaphragm and electric actuator
ranges. The free-float design provides
users with longer stem-seal life and
improved valve shut-off performance.
