The
N-2640 Series Hydra-Check Dispensers are unique
Constant Flow Rate, Positive Piston Displacement,
Double Acting metering units. They are used
to dispense viscous fluids and pastes with viscosities
as high as 3 McP and at pressures up to 3000
psi. They can provide a continuous and constant
flow of material that is pressure and temperature
compensated. What is unique about these dispensers
is that they can do all of this without
a hydraulic, electrical or pneumatic power package.
The N-2640 Series Hydra-Check Dispensers include
a double acting metering unit that is powered
by the fluid pressure of the material supplied
to it by the supply pump(s). With supply pressure
driving the reciprocating motion of the metering
unit, a Heavy Duty Hydraulic cylinder coupled
to the metering unit and provided with Pressure
and Temperature Compensated Flow Controls provides
adjustable but repeatable flow regulation. With
the Hydra-Check system, pump stroke change-over
surges and material viscosity changes that affect
the flow can be eliminated.
The N-2640 Series Hydra-Check Dispensers have
a large double acting metering unit with a capacity
of nearly 30 in3 per stroke. This
ensures low reciprocating rates, which in turn
provides long service life. The metering unit
utilizes Jesco’s air operated Power Flow
Valves for both the Inlet and Outlet Valves
to the meter.
The N-2640 Series Hydra-Check Dispensers are
systems that are simple to operate and maintain.
They are entirely pneumatically controlled and
require no more than a standard shop air service
to operate.
Many optional features are available for the
N-2640 Series Hydra-Check Dispensers.
