The TNV-33 is a high-pressure fuel pump (injection pump) for diesel engines, supplied in multiple configurations to match specific engine installations. The pump meters and pressurizes fuel across eight injector sections, with 9 mm plunger diameter and 10 mm plunger stroke delivering a nominal cycle feed of 5 units per cycle — the precision-machined heart of mechanical diesel fuel systems on eight-cylinder engines.
Mechanical injection pumps of this type remain the standard across vast fleets of trucks, tractors, generators and industrial engines, where their independence from electronics is an operational virtue: they are rebuildable, tolerant of fuel quality variations, and serviceable by any diesel fuel-system workshop. Configuration variants allow matching to different engine models and drive arrangements.
At around 900 dollars with a two-unit minimum, the TNV-33 addresses diesel service centers, fuel-system rebuilders, fleet maintenance operations and parts distributors supporting eight-cylinder mechanical diesel engines across agriculture, transport and power generation.
