Franklin Electric Warranty — Extendable to 36 Months

Franklin Electric warrants the package against defects in workmanship and material for 12 months from the date of install or 24 months from the date of manufacture, whichever occurs first. A completed and approved Start Up and Commissioning Checklist extends the warranty to 36 months from the date of installation. The form is on the Data Sheet tab.

Overview

The VR SpecPAK is a pre-engineered booster system that uses an integrated PLC controller, a user-friendly HMI screen, and a variable frequency drive to intelligently increase water pressure while maintaining a constant, reliable output.

It is an integrated pump package featuring multiple Franklin Electric VR Series vertical multistage pumps connected in parallel on a welded frame. The system’s intelligence resides in a central control panel equipped with a Programmable Logic Controller (PLC) and Human Machine Interface (HMI). The PLC automatically rotates the lead pump to ensure even wear and maximize the system’s service life, and the system is designed to maintain constant pressure even if one of the pumps has failed.

VR Series pumps feature an all 316 stainless steel rotating assembly for durability, efficiency and performance. They suit water supply and pressure boosting systems including HVAC, water treatment, irrigation and agriculture. From the HMI the operator updates the overall system control settings as well as many of the parameters on the individual VFDs, so the pumps are controlled as a package instead of individually.

The package arrives pre-assembled with a main disconnect and individual circuit isolation, allowing a single pump to be serviced without shutting down the entire system.

Genuine Franklin Electric equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier.
Available as Duplex, Triplex or Quadplex

This listing is the Triplex (3-pump) system. The same pump models are also built as Duplex or Quadplex. Every configuration ships factory-assembled on one frame with a single panel staging the pumps, and each added pump adds flow and gives you a spare if one goes down. The pump count is chosen at purchase.

More pumps hold more pressure at the flow the building actually draws. Each pump carries a share of the water, so each sits higher on its own curve. The shut-off pressure at zero flow is the one figure fixed by the pump model.

Key Features
  • Color touchscreen PLC control — system control without opening the panel; operators view system status, monitor pressure and adjust settings on the 7 in screen.
  • Modbus — remote monitoring and control.
  • Lead/lag or parallel operation — selected in system settings; the PLC rotates the lead pump for even wear.
  • Fused branch disconnects — an offline pump receives maintenance while the remaining pumps stay online.
  • Keeps running on a drive fault — on a failure or loss of power to any VFD, all of the remaining drives continue to operate.
  • Backup discharge transducer — one primary and one backup, so a lost sensor signal leaves the building with pressure.
  • Cerus X-Drive VFDs — variable speed control for the NEMA standard TC frame motors.
  • Stainless steel wetted components — corrosion resistance and uncompromised water quality; 316 stainless steel manifolds standard.
  • Field programmable — accepts firmware updates.
  • Ships programmed and tested — for easy startup on site.

Performance — Will It Do What You Need?

The figures below are the pressure this system adds. That is what a pump curve measures — the impeller does not know what pressure is already on its inlet. Max flow and max boost are the two ends of each curve, never a duty point: max boost happens at zero flow, and max flow happens at the lowest pressure in the row. Size to the column at your peak flow.

Zero flow is the shut-off point — a ceiling, not a working point. Figures are Franklin Electric’s tabulated 60 Hz hydraulic performance for each VR pump with full-diameter impellers (VR Series 60 Hz product catalog 00105042, 06/2020; guaranteed to ISO 9906:2012 grade 3B), converted from metres of head to psi, with flow multiplied by the pump count for all pumps running. The drives hold any lower pressure by running slower. Convert psi to head by dividing by 0.433. The exact model is confirmed in Franklin FE Select with every quote.

Drawing from a tank or cistern — nothing arrives with pressure, so what the pumps add is what you get. The 45VR 3-Stage system at 714 GPM delivers 121 psi.

Fed by a city main — the pumps add on top of what already arrives, and the controller holds the discharge setpoint you enter at the touchscreen. On a main delivering 40 psi, that same system can reach 161 psi at 714 GPM; set it lower and the incoming pressure buys you more flow at that setpoint.

Ask for more flow than the system can deliver at your setting and the pumps run at full speed continuously, which is where motors and seals wear out. Sizing a booster to the building rather than to the headline numbers is what makes it last.

How It Holds Pressure
Function How it works
Constant pressure control A pressure control loop holds the discharge setpoint entered at the touchscreen. In Auto mode the panel starts, stops and speeds the pumps on its own to maintain it.
Lead and lag staging A lag pump starts when the lead pump is above the Lag Start Speed and system pressure stays under 95% of setpoint for the Stage On Delay. The last lag pump stops when the lead pump is below the Lag Stop Speed and pressure holds at 98% of setpoint or better for the Stage Off Delay.
Alternation Switches the lead and lag pump designation to spread run hours across every pump. Interval alternation is on elapsed time.
Sleep mode When the setpoint is met with no demand, all pumps stop. The Wake Pressure restarts them; the default wake offset is 5 PSI, so a 70 PSI setpoint wakes below 65 PSI. Widening that deadband gives longer sleep periods between run calls.
System response tuning Slow, Medium, Fast or Custom PID response, with P-Gain, I-Time and Ramp Time open to adjustment in Custom.
Auto and Manual modes Auto runs the pumps to the setpoint. Manual lets an operator start and stop each pump and set its speed between the minimum and maximum manual speeds.
Drive settings from one screen Motor HP, voltage, RPM, FLA and frequency, acceleration and deceleration time and rotation are set at the HMI, and pump 1 settings can be applied to all pumps in one press.
Protection, Logs & Security
Protection or record What it does
Low suction pressure Warning or fault at a set pressure after a set delay. A fault stops the system before the pumps run short of water.
Overpressure The system stops when discharge pressure passes the overpressure level, then restarts automatically.
Low discharge pressure Optional fault when discharge pressure falls below its setpoint, for a burst line or lost supply.
Backup discharge transducer If the primary discharge transducer signal is lost, the backup carries on and the panel logs a warning.
Sensor loss Each sensor can be set to log a warning and keep running, or to fault and stop.
Tank level detection Filling or draining tank modes with separate warning and fault levels, for systems drawing from or filling a tank.
Underload Monitors each pump for an underload condition to protect it from running dry.
Current stall prevention Protects each motor from overcurrent when drive output frequency outpaces motor speed.
Fault log All active and past faults, timestamped on acknowledgement, with an alarm buzzer and a filter by pump number.
Data log Pressure and power readings over time, with two data sets compared on one graph.
Pump details Output voltage, current and power, DC bus voltage and IGBT temperature for every drive.
Password levels Settings are locked behind user accounts so only authorized operators can change them.

Installation — What the Installer Provides and Connects
Item What the installer needs to know
Site water connections Grooved. Suction and discharge can each be piped to either end of its manifold; the supplied end cap and coupling close the other end.
Isolation valves at the package Supplied by the installer, near both the inlet and the outlet. They ease startup loads and hold the discharge line full during maintenance.
Pressure relief valve Supplied by the installer, sized to pass full pump flow, mounted near the discharge and piped to a drain that can take full system flow.
Thermal relief valves Pipe each outlet to a suitable drain.
Power One feed to the panel disconnect, with ground to the panel grounding bar. The drives and panel arrive pre-wired. Size power and ground wiring to the panel nameplate.
Venting Pressurize the suction header with site water and vent each pump in turn at the 1-1/4 in plug on the discharge header end cap before first start.
Handling Forklift by the fork pockets, tines fully inserted, by a certified operator.

Before You Buy — The Limits That Decide the Fit
Discharge setpoint Entered at the touchscreen. The pressure each model can hold at your flow is in the Performance tables above; the max boost figure is the zero-flow ceiling, so size to the table column at your peak flow.
Maximum system pressure Incoming pressure plus pressure added must stay inside the pump casing rating. Franklin lists the round-flange VR pump at 360 psi maximum allowable working pressure.
Suction Built for a flooded or pressurized suction. The suction transducer reads inlet pressure and the low suction protection stops the system when supply falls away.
Power 460V 3 phase on every model listed here. Other voltages are separate builds, so confirm the service before ordering.
Indoor installation NEMA 1 panel, 104°F maximum ambient. Plan for a conditioned mechanical room.
Relief valve A full-flow pressure relief valve on the discharge is required and is supplied by the installer.
Pressure tank A hydropneumatic tank on the discharge lets the system sleep at low demand. A thermal expansion tank is still required at any storage water heater.
Pump count 3 pumps, fixed at purchase.
Freight and rigging Ships by truck on its own frame. Confirm door widths and the path to the mechanical room.
Indoor Installation — Installer-Supplied Relief Valve RequiredThe control panel is NEMA 1 rated and is installed indoors in a controlled environment. Pumps can develop very high pressure, so Franklin requires a pressure relief valve able to pass the full pump flow, installed near the discharge and routed to a drain capable of full system flow. Keep the panel fan filters clean and in place, and keep the HMI out of direct sunlight.
Before You OrderThese systems are built to order. We confirm the pump model, stage count and motor against your flow and pressure in Franklin FE Select and send the factory submittal for approval before the order is released.
