Introduction to VP1000-5 Vacuum Pump
The VP1000-5 Vacuum Pump runs on a 110 VAC source, is controlled by the MC100-1 control module, and is activated
for each transaction to provide the appropriate vacuum for the Healy nozzle to collect vapors at the vehicle fillpipe. The
VP1000-5 is typically installed in the lower hazardous area of a pressure or suction dispenser as shown in Figure 1.
One VP1000-5 pump is installed per dispenser to accommodate the vapor recovery needs for both sides of the
dispenser. When the dispenser is authorized, the MC100-1 will activate the VP1000-5 simultaneously and run at a low
speed (approximately 10 GPM). If both sides of the dispenser are authorized the VP1000-5 will run at a high speed
(approximately 20 GPM). The VP1000-5 has a thermistor circuit that allows the pump to activate when temperatures are
less than approximately 40°F in order to keep internal parts from locking up.
