Some answers to frequently asked questions about high pressure misting pumps. We now have the wonderful Variable frequency drive (VFD) pumps also known as inverter drive pumps or variable speed mist pumps. We have a few in stock to choose from and can custom build most any size.
We always carry Pulley Drive Mist Pumps and Direct Drive High Pressure Mist Pumps in stock. They both have their pros and cons:
Advanced Systems Direct Drive Mist Pumps
Most Direct drive misting pumps are usually the least expensive and most common although they can and in most cases be the loudest, This is due to the pump and motor spinning at 1750 rpm and they are usually maxed out at 1000 psi. Although the .5 and 1 gpm mist pumps are not too loud at all. The pump would shut off and not burn up. We have these mist pumps both with and without enclosures. We do suggest a low-‐pressure safety option to prevent damage to the pump if the water was ever turned off accidentally.
Advanced Systems Pulley Drive Mist Pumps
Pulley Drive Mist Pumps are typically more expensive than direct drive because of the extra cost of the pulleys, belts, and all the extra hardware that goes with it. All of the belt drive mist pumps are built with full enclosures that house all the electrical components and eliminates the need for a belt guard. One of the advantages of choosing a belt drive mist pump system is the noise factor; they are quiet and last much longer than the Direct Drive Pumps. The fact is that we size the pumps gallon per minute output much larger and then we slow the pumps down to about 750 rpm. This makes a large pump run much slower and produce less noise. These are good pumps for residential use.
Advanced Misting Systems Variable Frequency Drive Misting Pumps (VDF)
VDF’s are the most expensive mist pump option and these pumps have their own unique characteristics. They consume approximately 25% less electricity than non-‐VDF systems due to the inclusion of the VFD inverter and the way it utilizes electricity. This is one of the first of three electricity related efficiencies associated with a VFD mist pump but it is the primary reason VFD units are desired for many commercial and industrial applications.
Because of the inclusion of a pressure transducer in the Advanced Misting System VFD Misting Pump, the system also provides the unique capability of only turning the motor at the required hertz based on the flow demand at any given time. This unique feature provides a variable operating speed for the motor. In most cases, the motor AND the pump are both spinning at an rpm level that is less than a standard Direct Drive or Pulley Drive unit. The result is not only a substantially quieter operating mist pump, but also a mist pump that requires less electricity to operate. This is the second of three electricity related efficiencies associated with a VFD misting pump.
