B4 SERIES (GEAR PUMP)
B4 GEAR
Melters with gear pump for low and medium consumption
'Plug and work'
The B4 has been specifically to suit manual
and "low cost" automatic applications. The
unit will melt adhesive at a maximum rate of
6kg per hour.
Two Pump Styles
The gear pump version has a maximum
pumping rate of 6kg per hour and a pressure
relief valve to ensure a smooth delivery of the
adhesive. The relief valve is easily adjusted
from the outside of the melter. The piston
pump version has a maximum pumping rate
of 65kg per hour. The pressure regulator and
gauge are also accessible from the outside of
the melter allowing for easy adjustment.
Electronic Control unit
The electronic control of the B4 has been
developed using the same proven design
principles of all the new Meler products and
it's simple and reliable operation provides
temperature control from 40 °C to 200 °C with
an accuracy of ± 0.5 °C.
Hose Connections
The B4 has two hydraulic and electrical
hose connections to the rear of the unit. The
hydraulic connections are industry standard
9/16 JIC and the electrical connections are
available in the compatible form of PT100 or
Ni120.
Compatibility
Compatibility is one of the main characteristics
of B4 melters. They have been designed to
be compatible with either PT100 or Ni120
temperature sensors and can therefore
replace most hot melt equipment in the
market.
Tank
The melting tank of the B4 has a large surface
area which gives an optimal melting rate.
The tank has a large lid for loading adhesive
and has a filter and drain valve for ease of
maintenance.
Pump Motor
The B4 gear unit has a stop/start switch for
the motor and an external electrical input for
automatically starting the pump motor by the
main machine.
B4 VS
B4VS PUR
B4VS PUR is a melting unit for low and medium consumption for reactive adhesives.
Variable Flow
This device offers a wide range of manual and automatic flow adjustment options, by regulating the speed of the pump motor from 0 to 100 rpm.
Electronic control
B4 controls temperatures with a high degree of accuracy, from 40 to 200 degrees. Its safety system controls the following:
-Breakage of the temperature sensor and over excess temperature.
- Protects against application malfunctions.
- Communication with the main machine when the selected temperatures of all items have been reached.
Hose connection
B4 has two connections for the hose-applicator assembly. The hydraulic connections comply with the 9/16 18 UNF industrial standard.
Holding capacity
This unit is designed to melt small PUR blocks of up to 3 kg. Once the device has been loaded, the adhesive is protected by an airtight cover and humidity-free gas injection system.
Thanks to its design, B4VS PUR is easy to clean and maintain.
