This is a centrifugal pump unit, consisting of a pump and a motor mounted together on a base. It is designed for transferring clean, non-aggressive liquids in industrial, commercial, or agricultural applications (like water supply, circulation, pressure boosting, etc.).
1. Pump Details: FUJITA HCF-50B
- Manufacturer: Fujita Seisakusho (a well-known Japanese manufacturer of pumps and water treatment equipment).
- Model: HCF-50B
- HCF Series: Typically indicates a standard, horizontal, single-stage, end-suction centrifugal pump. These are general-purpose, durable pumps.
- 50: Likely refers to the nominal discharge port diameter in millimeters (approx. 2 inches).
- B: Often denotes a specific frame size, impeller diameter, or performance variant within the 50mm model line.
- Serial Number / Production Code: 371041 – This is a unique identifier for this specific pump unit, used for tracking manufacturing details.
- Type: Centrifugal Pump. This means it uses a rotating impeller to impart kinetic energy to the fluid, converting it to pressure for flow.
Typical HCF Series Specifications (for reference – exact specs vary):
- Port Size: Suction and discharge are often the same, likely 50mm (2″).
- Capacity/Flow Rate: Possibly in the range of 10-30 cubic meters per hour (approx. 40-130 US GPM), depending on the specific “B” trim.
- Head Pressure: Estimated range of 15-30 meters.
- Construction: Casing and impeller are likely made of cast iron for general use, with possible bronze or stainless steel options for other variants.
- Seal Type: Standard mechanical seal.
2. Motor Details: TIT90L JG Induction Motor
- Manufacturer: Likely a motor brand used by or affiliated with Fujita, such as Toshiba (TIT might stand for Toshiba Induction Motor), or another manufacturer like TEC.
- Model Designation: TIT90L
- TIT: Manufacturer series code.
- 90: Frame size. A “90” frame is a standardized metric (IEC) frame, indicating the physical dimensions and mounting. This is a common industrial motor size.
- L: Usually indicates a Long shaft or a specific mechanical construction variant.
- Type: JG Induction Motor.
- JG: This is a critical designation. In Japanese industrial standards, “JG” typically refers to a motor that is compliant with Japanese Government standards for small and medium three-phase induction motors. It signifies specific performance and construction standards.
- Key Motor Characteristics (Inferred from JG Standard):
- Phase: Three-Phase (3φ) power supply.
- Voltage/Frequency: Common ratings are 200V/50Hz, 220V/60Hz, or 400V/50Hz (specific to the Japanese/Asian market and export models). You MUST check the motor nameplate for the exact voltage.
- Output Power: For a 90L frame, common power ratings are 1.5 kW (2 HP) or 2.2 kW (3 HP). The nameplate will state kW/HP.
- Insulation Class: Usually Class B or F.
- Protection Class: Likely IP55 (dust-proof and water jet protected) for industrial use.
- Duty: Continuous (S1)
