Adaptable and Reliable Pump | Primeroyal N (PN)

The PRIMEROYAL N (PN) metering pump combines field-proven reliability with precision dosing capabilities across a broad range of industrial processes at flow rates that can reach up to 2,284 gph (8,649 l/h) for pressures up to 14,996 psi (1,034 bar).

The PN is used in many industrial processes due to its modular design which offers several types of liquid ends, capacity control, and other configuration options to meet the specific requirements of your process application.

Precision Dosing

Delivers highly accurate chemical injection with ±1% steady-state accuracy across a 10–100% flow range.

Variable Eccentric Drive

Innovative drive mechanism enables smooth stroke adjustment by repositioning the eccentric shaft center.

High-Pressure Capability

Handles pressures up to 14,996 psi (1034 bar), ideal for demanding industrial applications.

High Flow Performance

Supports flow rates up to 2,605 gph (9863 lph), covering both medium and large-scale processes.

Flexible Flow Control

Manual or remote adjustment with micrometric stroke control for precise dosing—even during operation.

Durable Material Options

Available in 316L Stainless Steel, 17.4-PH, and PVC for compatibility with a wide range of chemicals.

Modular & Compact Design

Customizable with multiple liquid-end options and adaptable configurations, available in vertical or horizontal layouts.

Enhanced Safety & Protection

Leak-proof diaphragm design, integrated overpressure safety valve, and compliance with global safety standards.

Versatile Industrial Applications

Used across oil & gas, chemical processing, refining, water treatment, and general industrial operations.
