Consistently Accurate Primeroyal L (PL) Series Metering Pump

The PRIMEROYAL L (PL) metering pumps are built to deliver consistent and accurate dosing for a wide variety of fluids at pressures up to 14,996 psi (1,034 bar) and a maximum flow rate of up to 1,164 gph (4,410 l/h) per dosing head. With proven ±1% steady-state accuracy and a robust, compact eccentric drive system, the PL pumps provide dependable operation from 10% to 100% of nominal flow. Thanks to their modular construction and multiple choice of liquid ends, the PL series pumps are perfect for industries needing flexibility without compromising on precision.

Engineered for water treatment and industrial processes, the PRIMEROYAL L (PL) combines reliability, safety, and durability to ensure you get the accurate dosing required by your process specifications.

  • Material (liquid end): 316L S.S. / 17.4-PH / PVC
  • Pressure max:
    • Diaphragm liquid end: 14996 psi / 1034 bar (metallic liquid end); 116 psi / 8 bar (plastic liquid end)
    • Plunger liquid end: 14503 psi / 1000 bar (metallic liquid end)
  • Flow max:
    • Diaphragm liquid end: 1164 gph / 4410 lph (metallic liquid end); 940 gph / 3561 lph (plastic liquid end)
    • Plunger liquid end: 919 gph / 3480 lph (metallic liquid end)
  • Multiplexing capabilities
  • Flow variation control: Manual / Remote
  • Certifications: API 675, EC, ATEX, IECEX

Like all PRIMEROYAL metering pumps, the PL is built to run continually all year long with preventative maintenance, leading to decades of consistent performance.

  • Compliant with API 675 standards
  • Adaptability and accuracy: capacity adjustable while running or stopped (stroke micrometric adjustment, 10 turns only from 0 to 100%, graduation scale in %)
  • Space constraints: Minimized footprint and weight, available in vertical or horizontal motor configurations
  • Suitable for the majority of fluids in all industrial and WWT processes: many stroke speeds for accurate dosing
  • Modular design to precisely fit your needs: multiple options for liquid ends, check valves, connection types, control, and more
  • Multiplexing capability: providing cost savings in the power consumption and asset footprint while reducing pulsation and required NPSH and, giving the capability to inject several different products or meet a specific flow rate
  • Long life: ensured by using high quality materials engineered to a robust and proven construction, oil bath lubrication to ensure reliability during continuous operation
  • Safety: diaphragm liquid ends guaranteed leak-proof with service life in excess of 20,000 hours
  • Operations even in the most extreme conditions: specific configurations to operate in saline/offshore conditions, desert, or low temperature environment
  • Global design: can comply with the main worldwide certifications and systems: ATEX, NACE, SASO, Customs Union, etc.
  • Overpressure protection: integrated safety valve to protect the pump on diaphragm liquid ends
  • Additional benefits with PTFE diaphragm liquid ends:
  • Maintenance easy and fast: the patented Mechanically Actuated Refill System (MARS) avoids the need to delicately adjust the refill valve
