1500 LPM HIGH FLOW ATF TRANSFER PUMP SUPPLY IN ASSAM To design a vane pump for ATF (Automatic Transmission Fluid) fuel transfer with a 1500 LPM flow rate and ATEX motor requirements, you need to consider the following key specifications and features: 1. Flow Rate: • Flow Rate: 1500 LPM (Liters per Minute), which is a high-flow requirement for fuel transfer. • Ensure that the pump is capable of handling this flow rate continuously without overheating or failure. 2. Pump Type: Vane Pump • Vane pumps are often used for fuel transfer applications due to their ability to handle both low and high viscosity fluids like ATF. The vane design provides smooth flow and minimal pulsation, which is ideal for consistent fuel transfer. • Vane pumps typically feature a rotor with sliding vanes that create expanding and contracting chambers to transfer fluid. 3. ATEX Certification (Explosion-Proof Motor): • ATEX Certification: Since the pump will be used for fuel transfer, which involves flammable liquids, the motor and pump assembly must meet ATEX (Atmosphères Explosibles) standards for equipment used in explosive atmospheres. • ATEX Zone: Determine the ATEX Zone of the environment where the pump will operate (e.g., Zone 1 or Zone 2 for gas or Zone 21 or Zone 22 for dust). • The motor needs to be rated for Category 2 or Category 3, depending on the zone classification. • The motor should also be explosion-proof, meaning it will not create sparks or excessive heat that could ignite flammable gases or vapors. 4. Material of Construction: • Pump Housing: The pump should be made of materials resistant to corrosion and wear, like cast iron, aluminum, or stainless steel, depending on the fluid's chemical properties and the operating environment. • Seals and O-Rings: Use materials like Viton or Buna-N for sealing, which are compatible with ATF fluids. 5. Viscosity & Fluid Compatibility: • ATF has a certain viscosity, so the pump should be rated for the viscosity range of the fluid. Ensure the pump is designed to handle the viscosity of ATF without excessive wear on the vanes or seals. • Ensure compatibility with other lubricants and chemicals that might be in the fluid. 6. Pressure & Suction Requirements: • The pump should be capable of handling the required suction pressure and discharge pressure. Vane pumps typically work in a range of pressures, but the operating pressure will depend on the specific transfer system and distance. • Suction Pressure: The pump should have a good NPSH (Net Positive Suction Head) to avoid cavitation. 7. Motor Specifications: • Motor Type: Explosion-proof electric motor (ATEX certified). • Power Rating: Ensure that the motor is sized correctly to handle the required flow rate (1500 LPM) and the pressure requirements of the system. • Voltage and Frequency: Choose the motor's voltage (e.g., 380V, 440V) and frequency (50 Hz or 60 Hz) based on your local electrical supply. • Speed Control: You may want to have a motor with variable speed control if you need to adjust flow rates. 8. Safety and Compliance: • Ensure the entire system complies with local safety standards, such as ATEX 95 (for equipment used in explosive atmospheres) and ATEX 137 (for workplace safety). • The pump and motor should have thermal protection and overload protection. Example Specifications for the Pump: • Pump Type: Vane Pump, designed for ATF. • Flow Rate: 1500 LPM. • Pump Housing Material: Cast Iron or Stainless Steel. • Pump Seal Material: Viton or Buna-N. • Explosion-Proof Motor: ATEX-certified motor, suitable for Zone 1 or Zone 2 applications. • Discharge Pressure: 4 to 6 bar (depending on your application). • Motor Power: Typically, for 1500 LPM at moderate pressures, a 15-30 kW motor might be needed. • Viscosity Range: Compatible with ATF fluid (approximately 30-100 cSt). • Temperature Range: Operates in a temperature range of -20°C to 60°C (depending on the motor and fluid).
