Knight Equipment PMPE-550V User Manual

Chemical Metering System

The PMP Plus Series is Knight’s newest line of variable speed metering pumps built on the
industry’s most reliable and consistent platform. The high performance chemical metering
system is designed to offer a wide array of flow rates and multi-functional controls to meet your
pumping application needs. With the choice of peristaltic or electric diaphragm metering
pumps, the PMP Plus offers the versatility to dispense a variety of process fluids or chemicals for
food & beverage cleaning and sanitation, dairy farms, industrial process, and large laundry.

INDUSTRIAL SYSTEMS

 New multi-function electronics with high resolution variable speed control (manual adjustment or

4—20 mA input) to vary pump delivery volume depending on the application

 One pump can serve a variety of your applications and reduce the need to stock multiple flow rates
 Optimize delivery speed for more efficient cleaning and reduced cycle time
 “All in One” control with selectable operating modes (limit timer, repeat cycle, relay input)
 PMP Plus Series offers the choice of Electric Diaphragm Pumps (2.8 gpm, 1.2 gpm, .6 gpm) [10.6 lit/

min, 4.5 lit/min, 2.3 lit/min] or Peristaltic Metering Pumps (.6 gpm, .25 gpm) [2.3 lit/min, 1 lit/min]

 Simple dip switch and push button programming
 Watertight, secure locking enclosure with powder coated IP-65 rated stainless steel
 Case mounted manual start activation or remote switch
 Delay on and lock out functions

PMP Plus Electric Diaphragm Pump (PMPE)

The PMP Plus Electric Diaphragm Pump is a highly reliable and simple design with few moving parts
that features a heavy duty, long life motor that produces high pressure yet, low pulsation pumping
action. These field proven pumps are engineered for aggressive chemical, high duty cycle
applications.

 High resolution variable speed controls allow you to “dial in” the precise flow rate required for a

wide variety of metering applications

 Flow Rates: 3.1, 2.8, 1.2 and .6 gal/min (11.6, 10.6, 4.5 and 2.3 lit/min)

 Long lasting EPDM or Viton seals for a variety of chemicals

 More consistent dosing as flow rates “hold” for life of the valves

 No squeeze tubes to change or service

 Quick connect “bayonet” style inlet/outlet fittings

 Continuous duty rated motors

 Engineered for aggressive chemical, high duty cycle applications

 70 PSI (4.83 bar) pressure switch option

PMP Plus Peristaltic Metering Pump (PMPP)

The PMP Plus Peristaltic Metering Pump System features
Knight’s industry best peristaltic pump design that has
become the bench mark for reliablity and quality for the
chemical dispensing industry.

 High resolution variable speed control allows you to

“dial in” the precise flow rate required for a wide
variety of metering applications
