Constant Pressure Systems

Some wells have a low production rate of less than 8 Gallons Per Minute (GPM). To keep up with your household water demands it may be required to have a reserve of water on hand from your well. The water is pumped from your well at its capacity rate (2-7 GPM) into the Cistern tank (below) where it is stored for use when required. Our MONO DRIVE Constant Pressure System uses a 3/4 Horse Power Submersible pump which is inside the Cistern tank which delivers water at a constant pressure through-out your home, acreage or farm. MonoDrive Constant Pressure Controller for Single Phase Pumps The MonoDrive is the newest technological innovation in the constant pressure market. The MonoDrive provides the flexibility to convert a single phase conventional pump system to a constant pressure system with a simple replacement of a 3-wire control box. Application Data The MonoDrive is designed for use in residential applications with a Franklin Electric 1/2, 3/4 or 1 Hp, single phase, 3-wire pump that is already in-place. It is great for homes that have a wide range of flow demand with performance requirements in the 1/2, 3/4 or 1 Hp range.

Features and Benefits:

• 1/2, 3/4 or 1 Hp performance + Constant pressure with a wide range of settings (25 to 80psi).
• Easy installation - remove the 3-wire control box, install the MonoDrive.
• Selectable Hp rating (1/2, 3/4 or 1 Hp).
• Works with a standard single phase 1/2, 3/4 or 1 Hp pump.
  • Any pump brand
  • No need to pull the pump
• If the MonoDrive is damaged, it can be replaced with a 3-wire control box until a new MonoDrive is installed.
• Works with small pressure tanks or larger tanks already in place.
  • Minimum tank volume: 2 gallons
  • Make more room for storage space.
• Excellent radio frequency interference shielding.
• Installation is as simple as a control box.
• Soft start means less motor stress and longer motor life.
• Built-in diagnostics and protection.
  • Surge protection
  • Open circuit
  • Underload
  • Short circuit
  • Under voltage
  • Overheated controller
  • Locked pump
• Smart Reset® technology allows well recovery before restarting the pump.
• UL recognized for U.S.A. and Canada.
• The MonoDrive is configured at the factory to work on a 3/4 Hp pump and motor.
• A jumper on the printed circuit board of the MonoDrive allows for the selection between 1/2, 3/4 and 1 Hp operation (Figure 1).
• An excellent upgrade option for the customer when replacing a pressure tank. Instead of another large tank, install a small tank and a MonoDrive. The customer has a new tank, more room, and constant pressure.
• Installation is as simple as a 3-wire control box.
• You can provide your customers all the advantages of an electronic constant pressure water system without pulling the pump!
