LIQUIPORT®
KNF
NF series of liquid pumps are the convenient
way to transfer liquids in the laboratory. They
are resistant to chemical attack, prevent contamination
of your pumped medium, and provide the longest
possible lifetime when pumping corrosive liquids,
gases and vapors. They are available with either
local or external control capabilities. External
protocols include: 0-10 VDC, Start/Stop via
TTL contact, and Output Fault Alarm.
The
NF100 and NF300 series are available in either
polypropylene, PVDF or PTFE head materials,
with FFPM valves, and as OEM
models.

Adjustable
Diaphragm Valves
This
diaphragm valve is small, can be continuously
adjusted and is suitable for air and
liquid. It can be used in many ways, e.g.
as an overpressure safety valve, inducing a
backpressure or preventing liquid from being
sucked / pushed through the pump.

Pulsation
Damper
This
pulsation damper eliminates up to 97%
of the outgoing pulsation and can be used for
different purposes: - reduction of vibration
in the hoses / pipes - protection
of expensive measuring instruments after the
pump - improving pulsation sensitive
processes

Metering Pump
|
|
STEPDOS®
Metering Pump
This
metering pump is designed for use with neutral
and aggressive liquids. They feature continuous
and steady flow, even at low rpm, using a stepper
motor that ensures that the suction cycle is
completed at maximum speed, but the output cycle
is variably controlled per selected speed. Constant
speed changes by the motor and electronic control
provide steady output over the entire cycle.
