POMPA TORISHIMA MHG / MHB MULTISTAGE PUMPS

	MHG/MHB MULTISTAGE PUMPS > MHG/MHB HIGH PRESSURE MULTI-STAGE DIFFUSER PUMP Principal fields of MHG segmental ring-section casing and MHB barrel casing pumps are; handling feed water in boiler plants, boiler feed and condensate handling in industrial plants and power stations, descaling plants, oil refinery and chemical plants. FEATURES 1.  MHG can be quickly started without any warming of casings 2.  The first stage impeller is single or double suction type 3.  Pump rotating parts of MHB can be removed without disconnecting the discharge or suction piping 4.  Major parts of MHG such as bearings, shaft seals and axial thrust balancing devices are      replaced without disconnecting the discharge or the suction piping 5. The rationalized range chart together with our individual development or hydraulics allow computer-aided selection to optimize either ; energy consumption, initial cost, NPSH value 6.  Rationalized production and stock-keeping system ensures shortest delivery times TECHNICAL DATA Total Head     H   up to 4,200 m (13800 ft) Capacity        Q   up to 1,440 m3/hr (6340 USgpm) Speed            n    up to 7,000 RPM Temperature   t    up to 200 Degree Celsius (392 Degree F) Model : MHG (Ring-section type), MHB (Barrel type) capacity (Max.) : 1,440 M3/hr. head (Max.) : 4,200 M. temperature : 350°C Speed : up to 7,000 RPM. material Casing :Carbon steel, Chrome steel Diffuser : 13% Chrome steel Impeller : 13% Chrome steel Balance : 13% Chrome steel Properties: Suitable for pumping water at very high pressure and temperature. In the petrochemical industry, power plant, Boiler feed pump, etc. The pump has a balance of thrust load that is made on the bearing set, resulting in long service life. Pump seals are available in both Packed gland seal and Mechanical seal. Inlet and outlet pipes can be selected as a flange according to JIS or ANSI Standard. For MHB models, the Welded method is used instead of the Barrel Casing, thus removing / assembling only the internal parts for easy maintenance.

                 

MHG Horizontal multistage ring section pump

                                      

Description

The TORISHIMA MHG is a horizontal multistage ring section pump specifically designed for high pressure services
such as power stations, incineration plants and HRSG in steel and nonferrous mill.
The simplified construction allows easy maintenance and quick overhaul, and no warming through is required for MHG.
Mechanical seals are equipped as standard and, blind stage and interstage tapping can be fitted as option for customized requirement.
The optimum pump design ensures total reliability and highly cost-effective solutions.

Technical Data

Total Head	up to 4,200m / 13,800ft
Capacity	up to 1,400m³/h / 6,100USgpm
Temperature	up to 200°C / 392°F
Pressure	up to 42MPa / 6,090psi
Size	50 to 125mm

MHB Radially split barrel casing pump

Description

The TORISHIMA MHB is a horizontal, radially split, multistage barrel casing pump.
Mainly applied for boiler feed applications in thermal power stations (sub-critical/super critical)
and combined cycle power stations.
The barrel casing is fully welded to the pipework and supported at its centerline on a fabricated steel baseplate.
The inner cartridge, which contains all pump components except the barrel and main stud bolts,
is removable from the barrel as a complete unit for ease of maintenance.
This optimized design of MHB results in high efficiency and high reliability,
subsequently reduces the operation and maintenance costs though the life of the station.

Technical Data

Total Head	up to 4,200m / 13,800ft
Capacity	up to 2,000m³/h / 8,800USgpm
Temperature	up to 230°C / 446°F
Suction pressure	up to 4MPa / 580psi
Discharge pressure	up to 42MPa / 6,090psi
Speed	up to 7,000min-1
