Pump know-how for LNG – Diesel and fuel turbine worldwide
New submersible centrifugal pumps from Vanzetti Engineering for liquefied pure fuel functions within the maritime sector
The Italian firm Vanzetti Engineering, specialist in cryogenic tools for liquefied pure fuel (LNG), has been engaged on liquid methane for marine functions since 2006, specifically for low strain LNG marine functions; in recent times, the corporate has additionally addressed excessive strain LNG marine functions.
Just lately, Vanzetti Engineering launched the brand new VT-3 reciprocating pump, designed and manufactured in accordance with the marine classification normal. The VT-3 pump can be utilized as a excessive strain pump to produce fuel to MAN two-stroke ME-GI engines. It’s out there in a Triplex configuration with a movement price of as much as 14 m3 / h and a strain of as much as 350 bar.
The VT-3 pump may also be skid mounted (additionally licensed for marine functions) and equipped with a variety of equipment together with sensors, devices and valves for secure and dependable pump management.
Vanzetti Engineering additionally affords the Artika collection of submersible centrifugal pumps, the fashions of which will be authorized by the required marine classification. Relying on the dimensions (proportional to the movement) and the variety of levels (proportional to the strain), these pumps can be utilized as:
- Spray pumps or bilge pumps on LNG carriers and LNG bunkers
- Foremost or standby pumps for the fuel provide of low strain marine engines, with a differential strain as much as 20 bar
- Small to medium cargo pumps
- Ship-to-ship bunker pumps
- Booster pumps for floating storage regasification unit (FSRU), with differential strain as much as 55 bar
The Artika collection pumps will be mounted on the backside of LNG tanks or inside vacuum cryostats put in on the base of the tanks. In each instances, these pumps, fitted with bearings always lubricated with LNG and with out seals, protect chilly temperature situations for quick and environment friendly start-stop operations and diminished upkeep.
Artika pumps can be found in a single-stage or multi-stage (2, 3, 4 or 6) configuration and have a helical inductor to attenuate the online constructive suction head (NPSH) required and an built-in motor to be used with the inverter or frequency converter. In keeping with Vanzetti Engineering, these pumps have a diminished noise emission, beneath 80 dB (A).
Artika submersible pumps can provide LNG at totally different movement charges and pressures. For instance, the bigger Artika 300-2S mannequin can obtain movement charges of as much as 300 m3 / h with a differential strain of as much as 12 bar.
The 2 collection of pumps – Artika and VT-3 – will be utilized to all varieties of LNG-fueled ships and convey collectively quite a lot of fascinating references: for instance, Vanzetti Engineering is the only provider of all cryogenic pumps for ships from Carnival Company cruise. by LNG engines.
The corporate additionally equipped the gasoline fuel system pumps for the Royal Doeksen LNG catamaran ferries, with significantly low movement ranges required. In keeping with Vanzetti Engineering, in these functions the Artika 120-3S mannequin ensures dependable and steady movement and strain beneath all working situations.
Container ships such because the Wes Amelie (transformed ship) or the Nordic Hamburg (new construct) symbolize a few of the many low movement functions for Artika pumps: within the first case for four-stroke engines, within the second for 2. WinGD X-DF racing engines.
Vanzetti Engineering additionally reported that the primary Put up Panamax transatlantic LNG carriers to be constructed, owned and operated by Siem Automotive Carriers can be fitted with MAN two-stroke ME-GI engines and VT-3 pumps from Vanzetti Engineering. Relying on the consumption wants of the motor, the VT-3 pump will be tailored by Vanzetti engineers in Simplex, Duplex or Triplex configuration.
