  • Mytee Escape LX-Plus:  Regulated to 1000 psi - What does this mean?

    Question: Mytee Escape LX-Plus: Regulated to 1000 psi - What does this mean?
    Answer: The pump that has always been installed in the Mytee Escape LX-Plus is the Mytee 359A or the 359B
    This includes an electric motor that is 1.5 Hp 56 Frame Motor
    In the past this is the M44, M64, or M5 Leeson. All these have been used in the past.
    The more you ask a water pump to push in GPM (gallons per minute) or in PSI (pounds per square inch) the more or higher the amp draw requirements are.
    When mated to the Pumptec 356U Pump head at 1200 psi uses 15 amps @ 120 volts.
    The same pump and motor assembly at 0-75 psi (garden hose pressure) use 7.5 amps. The amp draw increases with more pressure, so between 0 psi and 1200 makes up the balance of the remaining 7.5 amps.
    Each 160 psi will add 1 amp more @ 120 volts. 1000 psi = 6.25 amps for the psi + 7.5 amps to turn on = 13.75 amps @ 120 volts.
    If only cleaning carpet at 500 psi = 7.5 amps to turn on + 3.13 amps in pressure = 10.63 amps @ 120 volts.
    It is super important to have the machine be 10% under 15 amps because of the plug/outlet that this machines plus into.
    The power cord on the Escape LX-Plus is a NEMA 14-30P.
    The breaker in a home for this type of outlet is 30 amps. Wire resistance needs to be 10% under this load.
    In other words, you might be on a 50-foot power cord and this machine on a 4-foot cord draws 27 amps @ 240 volts but at 54 feet, this same machine can now draw 30 amps @ 240 volts.
    Example with accessory item 20210423
    The more distance electricity traves through the more wire resistance is created.
    There are two power halves to this outlet. You will see what I mean when you look at the breaker it will have two 30-amp breakers tied together. Each have is providing up to 30 amps @ 120 volts to this outlet.
    In other words, you can say it is providing 60 amps @ 120 volts or 30 amps at 240 volts. Both are equally correct.
    This machine is wired with 2 vacuum motors on side of the plug (average amp draw with wand on the floor 24.8 amps) but with the wand in the air or no vacuum hose at all the amp draw is a full 30 amps for two vacuum motors.
    The other half of the machine is one vacuum motor, (12.4 amps wand on the floor - 15 amps wand in the air or not hose) Plus the high-pressure water pump, regulated to 1000 psi 13.75 amp + 3.3-gallon auto dump pump 1 amp = 27.15 amps.
    If the pump was not turned down or prevented you from turning it up more, it could possibly trip the breaker.
    Another way to regulate the pressure is swap out the 1.5 horsepower motor with a 1 horsepower motor. A one horsepower 56 frame motor under full load draws 13.6 amps anyway.
    From an engineering standpoint, it is better to install a larger motor and turn down the water pressure than to place a smaller motor on the system and let is run at full capacity.
    All these machine have an pressure adjustment system on it. Visit
    This is how the pump is regulated. As you turn the knob clockwise it increases the water pressure as you turn counter-clockwise (anti-clockwise) creates less pressure.
    The factory can simply change the spring to a lighter duty spring inside the unloader so when you attempt to turn up to 1200 psi, the spring is simply does not offer enough back pressure to produce the resistance.
    Note Mytee installs this is a suction feed pump and not a pressure feed pump so your 'use' pressure will be hindered combined that Mytee installed a chemical injection system with will further reduce pump performance and life.

    We have additional articles in this forum on Pressure feed VS suction feed systems as well as the different types of chemical injection systems.
