The Jesco Ram Meter Series dispensers are constant flow rate, positive displacement dispensers that can meter low to high viscosity adhesives and sealers directly from the material supply container. They can dispense precisely metered shots or consistent diameter beads at an adjustable and repeatable flow rate.

Because of their Pressure and Temperature Compensated Hydraulic drive package, the Ram Meter Series of dispensers can efficiently and accurately meter materials with better flow control than can be obtained with a reciprocating barrel or pail pump. Since they meter directly from the original supply container, these dispensers do not require supply pumps. This offers the end-user lower overall equipment costs, requires less floor space for the equipment and simplifies / reduces the amount of equipment maintenance required.

Ram Meter Dispensers are available in several different versions, with a multitude of available options.

The N-1740 Series Ram Meter pictured above is a small capacity unit that includes a 5 Gallon, 3” double post elevator and 5 Gallon follower plate. This dispenser can meter materials up to 3 McP. It has a maximum capacity of 1.9 in³ per stroke and can dispense at pressures up to 3000 psi.

The N-1890 Series Ram Meter dispensers are standard with Jesco’s Constant Flow Rate Hydraulic Drive package. They include a 55 Gallon, 3” double post elevator and 55 Gallon follower plate. A 5 Gallon follower plate is optional. The N-1890 Series Ram Meter dispensers can meter viscous materials up to 3 McP. They have a maximum capacity of 35.7 in³ per stroke and can dispense at pressures up to 3000 psi.

The N-1890-AE Series Ram Meter pictured above represents a variation in the N-1890 Series of dispensers. The “-AE” suffix stands for Analog Electric dispenser. In this series, the standard Hydraulic Power Unit and Cylinder drive package is replaced with a DC Servo Motor and Inverted Ball-screw Actuator. With closed loop velocity control, this dispenser provides constant flow rates at any given setting. This type of dispenser also responds to an analog signal that is sent from the Robot that is proportional to the flow rate of material required. Analog response with a Hydraulic Drive Ram Meter is also available in the N-1890-AH (Analog Hydraulic) Series dispensers.

The N-1890-HV Series Ram Meter dispenser pictured above is the largest in the Ram Meter Series. This High Viscosity unit includes a 55 Gallon, 5 1/2” double post elevator with 55 Gallon high draft follower plate. This series of Ram Meters can dispense High Viscosity materials up to 12 McP. They have a maximum meter capacity of 61.8 in³ per stroke and can dispense at pressures up to 6000 psi. Some of the same variations available in the N-1890 Series Ram Meters are also available in the N-1890-HV Series.

All Ram Meter dispensers have various options available to customize their use in a given application. Options such as the “-ROB” option, which provides a Volume and Flow Rate Indicator and Alarm Package as well as Pin Receptacles for interface to a Robot or other Supervisory controller. Timed shot controls for Manual dispense applications. Various Applicator Valves to fit the application. Etc.
