Product Overview
JB-70 Electric & Manual Oil Metering Pump is a dual-mode dispensing pump that features both electric and manual operation, designed for safe and efficient oil transfer in fueling systems.
It solves the problem of maintaining continuous operation in the absence of power while providing precise fuel measurement and stable flow control.
Ideal for use in small to medium-sized fueling stations, industrial plants, agricultural machinery depots, and marine service points.
Applications
• Fueling stations and industrial plants
• Agricultural machinery depots for on-site fueling
• Marine service points for fueling boats and equipment
• Fleet workshops for fuel management
Engineering Advantages
• Dual-mode operation: Electric operation with a manual backup for uninterrupted dispensing, even during power outages.
• Explosion-proof motor: Designed for safe fuel transfer in hazardous environments with flammable media.
• Built-in metering system for precise fuel delivery and accurate volume measurement during dispensing.
• Integrated pressure relief/bypass circuit ensures safety by returning fuel to the tank under nozzle closure or overpressure conditions.

How to Select a Pump Model
• Identify the required flow rate based on fueling station or machinery requirements.
• Ensure the pump’s pressure rating matches system pressure needs.
• Choose a model based on media type (e.g., gasoline, diesel, lubricating oil).
• Select based on flowmeter accuracy class and dispensing precision requirements.
Engineering Notes
• Ensure adequate filtration to prevent contamination of the fuel and pump components.
• Monitor oil temperature to maintain optimal viscosity for smooth operation.
• Regularly check the V-belt drive system for wear and replace if necessary.
• Use the manual drive option if electrical power is unavailable or during emergency situations.
Compliance & Quality Assurance
• Factory performance testing to verify accuracy and flow stability.
• Hydraulic testing to confirm the pump’s efficiency under operational conditions.
• Material traceability for all wetted components to ensure quality and durability.
• Third-party inspection available for additional quality assurance.
Safety Notice
• Do not operate under dry-running conditions to avoid damage to the pump components.
• Ensure proper suction priming before operating the pump.
• Disconnect power before performing any maintenance or repairs.
• Regularly inspect the filter element to prevent clogging.
