Metering pump
The latest series of agricultural metering pumps from John Blue is dubbed the Next Generation Pump, or NGP.
The NGP incorporates the basic engineering traits of the L and LM pumps and uses the same footprint as the LM series for easy interchangeability. The series features a number of improvements over the previous L and LM pumps.
Single valve cap: One-piece valve cap allows for easy check valve access without removing the hoses. Service inspection and maintenance can be done in the field.

Nytro Ag Corp and Green Lightning recieved an innovation award at Ag in Motion 2025 for the Green Lightning Nitrogen Machine, which converts atmospheric nitrogen into a plant-usable form.
Outboard cylinder: Plunger packing can be inspected or replaced in the field without removing the hoses.
Main shaft seals: The newly designed main shaft seals incorporate a dual wiper that are enclosed in a grease cavity to flush out contamination, resulting in longer life.
Check valve: A positive check O-ring seal offers enhanced priming.
Universal piston rod seals: Pump life is maximized by the three-stage design V-packing wet end, back up V-packing protection for the crankcase and secondary O-ring seal to reduce crankcase weepage.
Standard main shafts: Standard single and double piston pump crankshafts are universal in the NGP line for modular upgrades such as clutches and on-the-go
variable rate.
Double-piston planter pump: NGP-8055 offers 42.0 gpm for
24-row planters.
Common or independent manifolds: The larger capacity NGP double piston pumps come standard with a common inlet and outlet manifold that can be removed for independent pumping chambers, allowing dual flow divider use or half width applications.
