Now Vanzetti Engineering is significantly increasing its deliveries of high-pressure pumps for marine use. This demand is due to the great demand in the sector that integrates the product type in the supply systems of marine engines. Since 2021, the number of orders for VT‑3 type cryogenic high-pressure piston pumps has increased significantly. This is due to the new market trend of using high-pressure systems. This particularly affects giant ships that run on natural gas, such as container ships, bulk carriers, gas and chemical tankers, and car carriers. Giancarlo Geninatti Crich, Vanzetti Engineering’s LNG Marine Sales Manager, confirms, “New ships are increasingly using methane engines for their propulsion systems. There is a high demand especially for high pressure systems. In this regard, the trend has changed — just a few years ago, low-pressure engines were preferred.”
More efficient and sustainable engines
This trend, which has emerged in recent years, has its origins in the technological development of engines in terms of sustainability and efficiency. ME-GI high-pressure two-stroke engines from the MAN company are used to power today’s giants of the seas. They use VT‑3 low-temperature piston pumps in a double, triple or quadruple configuration.
“Already in 2019, the company delivered the first products for high-pressure applications in the marine sector. By 2020, 90% of the cryogenic pumps sold in this sector had low-pressure technology (up to a maximum of 20 bar). Since the beginning of 2021, however, orders for high-pressure pumps (up to a maximum of 350 bar) have increased considerably. Our current order intake includes a 50% share of high-pressure and 50% of low-pressure pumps.”

From 2021 to date, the company has delivered a large number of VT‑3 machine groups in double and triple configuration for more than 30 vessels equipped with high-pressure supply systems and in demand worldwide, mainly from customers in China, Korea, Singapore and Norway.
Safety, reliability and low maintenance
Vanzetti Engineering’s VT‑3 cryogenic piston pumps are an evolution of the previous VT-55 model. Depending on the desired flow rate, the pumps are available in single, double, triple or quadruple configurations. Their maximum pressure is 420 bar. The VT‑3 model represents an ideal solution in terms of performance, safety, reliability and maintenance optimization. Its delivery can be made on a transport and installation frame that supports both the pump and all the accessories (sensors, instruments and valves) necessary for safe and reliable pump operation.Innovative high pressure pumps for the marine sector
