Vacuum pump

[LF_rookie_to_be]

Could anyone provide some more information on a Thomas vacuum pump? Here are the specifications from the Gardner Denver site:

Model Number: 007CDC19
Product Family / Type: Diaphragm
Operating Mode: Vacuum
Medium: Gas
Vacuum Flow Rate: 0.7 cfm / 18.4 l/min
Vacuum Continuous: 23.0 in.Hg / -780 mbar
Max Intermittent Vacuum: 23.0 in.Hg / -780 mbar
Max Vacuum Restart: 23.0 in.Hg / -780 mbar
Energy Supply: DC
Voltage: 12V
Motor Rating: 22.4 W
Current Drawn: 3.8 A
Motor Type: Permanent Magnet
Motor Protection Class: F
Speed: 2800 rpm
Weight: 2.90 lb / 1.30 kg
Ambient Temperature: min.50 °F / 10 °C
Ambient Temperature: max.104 °F / 40 °C
Stroke: 0.20 in / 4.8 mm

My questions are:
1. Is it perfectly safe to power it using a 12V/60W/5A AC/DC protected converter for halogen/LED lights?
2. Does it look powerful enough to give enough pull for, say, a 30x40" FB double-weight sheet (horizontal projection)?
3. Do the length and bends in the hose affect vacuum pull?

Thanks.
