VD (E3.1) 10/2020 page 31/179
BINDER vacuum pumps are designed for a gas inlet temperature of von max. 40 °C / 104°F.
Observe the permitted gas inlet temperature. The following values refer to the maximum ambient
temperature of the pump of 40 °C / 104 °F.
Operation condition
Inlet pressure
Permitted gas temperature
Continuous operation
> 100 mbar / 2.95 inHg (high gas load)
+10 °C to +40 °C / 50°F to 104°F
Continuous operation
< 100 mbar / 2.95 inHg (low gas load)
0 °C to +60 °C / 32°F to 140°F
Short-time operation (< 5 min.)
< 100 mbar / 2.95 inHg (low gas load)
-10 °C to +80 °C / 50°F to 176°F
Do not exceed the permitted gas inlet temperature. An excessive gas inlet temperature may diminish the
lifetime of the pump.
NOTICE
Danger of damage to the vacuum pump by exceeding the gas inlet temperature.
Impairment of the lifespan of the vacuum pump.
∅ Do NOT exceed the set-point temperature of the permitted gas temperature.
With higher set-point temperature, take appropriate measures to cool down the sucked-
in gas before its entry to the vacuum pump
4.4 Vacuum connection
Always connect the VD vacuum drying oven to a vacuum pump or to a domestic vacuum system. For this
purpose, the vacuum connection (6) with small flange DN16 must be connected to the back of the
chamber at the top with the vacuum pump or domestic vacuum system via a vacuum suction hose. For
connecting to the chamber, BINDER recommends the connection kit VD, Art. no. 8012-1995. The
optional pump module (Chap. 4.3) has a corresponding hose outlet on its rear.
Vacuum pumps with a suction capacity of 1-30 m³/h are suitable for the VD vacuum drying
oven.
4.4.1 VD connection kit for VAP1-VAP2 (option)
The VD connection kit (Art. no. 8012-1995) consists of:
• Aluminum straining ring DN10/16
• Outer centering ring DN10/16
• Small flange with hose tulles DN16/8
• 2.5 m / 98.4 in India rubber hose DN 8
• 2 hose clamps
