The N-1023, N-1190,
N-1264, N-1277 and N-1375 Series units represent
an extensive line of 2 Component, Positive Displacement,
Lance type Piston Metering, Constant Flow Rate
Dispensers. These dispensers were originally
developed to meter, mix and dispense 2 part
epoxies. As such, these units have unique features
that enable them to perform the task very well.
Like the N-888-CM Series dispensers, these units
are fixed ratio dispensers capable of dispensing
viscous materials up to 3 McP and at pressures
up to 3000 psi. They also include a Pressure
and Temperature Compensated Hydraulic Drive
Package that powers the metering cylinders and
provides Constant Flow Rate Capability. The
Power Flow Valves used as Meter Inlet and Outlet
Valves to the metering cylinders are the same
ones used on the N-888-CM Series dispensers.
Both Series share many of the same options.
But unlike the N-888-CM Series, these dispensers
are designed to meter, mix, and dispense materials
at the lower end of the volumetric ratio range,
from 1:1 to as high as 18:1 on some models.
These dispensers utilize 2 port versions of
the Jesco Roto-Stat Air Powered High Shear Dynamic
Mixer. They are available in 3 different sizes
to suit the flow rate and mixing requirements
of the application.
Many of the dispensers in this series include
a Quick Change Packing Design which greatly
facilitates the task of servicing the Meter
Packings. By removing 3 bolts, the metering
rod and packing set can be easily removed for
service, without the need to dismount the entire
metering cylinder or disrupt any plumbing to
or from it.
As can be seen from the photos, many variations
of these dispensers are available to suit nearly
any application. They can be used in Manual
Dispensing applications, or Fully Automated
Dispensing Cells when interfaced to a Robot
or other Supervisory Controller.
The various models available offer a wide range
of output capacities and flow rate capabilities.

stroke output for each model at a 1:1 ratio.
