Low Flow and High Pressure
Primeroyal PK and PKG Models

PRIMEROYAL metering pumps are versatile, reliable pumps that consistently and accurately inject chemicals. The pumps’ field-proven design enables precise control of the pump delivery rate with a +/-1% steady state accuracy ranging from 10 to 100% of the nominal flow rate. They feature a compact, variable eccentric drive that changes the stroke length by repositioning the center of the shaft in the eccentric.

Models PK and PKG provide accurate dosing of a broad spectrum of fluids used in many industrial processes due to their modular design which offers several types of liquid ends, capacity control and other configuration options to meet the specific requirements of your process application.

Low Flow and High Pressure
Primeroyal PK and PKG Models

Benefits:

Compliant with API675 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, GSD design for tiny spaces
Suitable for the majority of fluids in all industrial processes: many stroke speeds for accurate dosing
Modular design to precisely fit your needs: multiple options for liquid ends, check valves, connection types, and control…
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
- Triple hydraulic security with the GSD design: in addition to the internal pressure safety valve, the diaphragm controls the hydraulic refill and the diaphragm itself is protected by a valve blocking the overrunning and the extrusion
- Installation Monitoring Indicator (IMI) system with the GSD design: visual indication of overpressure, cavitation and lack of pulsation dampening that can cause disturbance and inaccuracy in the dosing process
