N-888-CM Series Two Component Conventional Viscosity Hydraulic Piston Meter Dispensers

The N-888-CM Series Dispensers comprise a very extensive line of 2 component, fixed ratio, Positive Displacement, Constant Flow Rate, Lance type Piston Metering dispensers. These dispensers were originally developed to meter, mix and dispense 2 part, 78:1 and 22:1 ratio by volume, Water Catalyzed Urethane adhesives in Automotive Glass Bonding applications.

Today, numerous versions of the N-888-CM Series dispensers are available to dispense virtually any 2 component material, at ratios from 10:1 to 80:1, with viscosities up to 2 Million CPS and at pressures up to 3000 psi. Whether the need is to dispense small, accurate and repeatable shots at very fast repetition rates or long, large cross-section, consistent and uniform beads of mixed material, there is an N-888-CM Series Dispenser available to do the job.

All of the N-888-CM Series dispensers offer an optional Jesco Roto-Stat Air Powered High Shear Dynamic Mixer. Available in 3 different sizes, this single port mixer is capable of producing uniform and consistent mixtures, even on the widest ratios and most difficult to mix 2 component chemistries.

All N-888-CM Series dispensers are constant flow rate machines. This is accomplished with the Pressure and Temperature compensated Hydraulic Drive Package that powers the metering cylinders. This feature provides consistent and repeatable flow rate control of the material dispensed, regardless of Time, Temperature, Pressure or Batch material characteristics that can vary.

PLC control logic is standard, & all N-888-CM Series dispensers include a control panel built to automotive electrical (JIC) standards. Standard controls include the following functionality at a minimum;

  • Automatic mixed material purge controls with adjustable purge duration, purge delay and purge interval timers.
  • Manual controls and indicator lights for operating the equipment and diagnosing major faults.

Other features available are the “-TS” Timed Shot control option that works together with the Heavy Duty P & T Compensated Hydraulic Drive package to provide accurate and repeatable shots. The “-ROB” option provides an interface to a Robot or other Supervisory controller and also includes a Volume and Flow Rate Indicator with High and Low Limits that facilitate monitoring and verifying process parameter requirements.

The N-888-CM Series dispensers are available in several different versions, each one uniquely capable of fulfilling the requirements of numerous applications.

The N-888-CM unit pictured above can dispense up to 20 in³ of 10:1 ratio mixed material per stroke and can be used in manual or automated dispensing cells. With a “-TS” option, this machine has been used to dispense repeatable and rapid fired shots.

There are many other versions of the N-888-CM Series dispensers available, too many to mention all of them here. So if you have a viscous, wide ratio, difficult to mix, 2 component material that needs to be dispensed accurately and repeatably, ask about the Jesco N-888-CM Series Dispensers.
