ZH-100A Hand-Operated Fuel Metering Pump

Product Overview

The ZH-100A Manual Fuel Metering Pump is a manually operated fuel transfer and metering device, designed for small to medium fuel storage and dispensing applications. The pump features a compact and lightweight structure, making it easy to transport and operate. A single operator can achieve continuous fuel transfer via the manual handle. The pump is equipped with a vertical YL-25 (DN25) mechanical flow meter, which includes a zero-reset pointer for clear and direct volume indication. An optional 1-inch fuel nozzle can be installed at the outlet for on/off control, effectively preventing fuel leakage.

Key Features

• Manual Operation: No external power required, allowing for continuous operation by a single operator.

• Compact and Lightweight: Easy to transport and install.

• Mechanical Flow Meter: Equipped with a zero-reset pointer for clear, direct volume reading.

• Optional Fuel Nozzle: A 1-inch fuel nozzle can be installed for on/off control, reducing leakage risk.

• Reliable Operation: High precision flow meter ensures accurate measurement and stable long-term use.

Engineering Overview

The ZH-100A uses a reciprocating piston principle, where the manual handle drives the piston to alternately draw and release fuel. The metering mechanism is integrated with the pump body to achieve accurate volume measurement during the transfer process. This design is ideal for environments where no electricity is required, or where simple, reliable manual control is needed.

Typical Applications

The ZH-100A is suitable for low-flow fuel transfer and metering, widely used in the following areas:

• Small to Medium Fuel Storage: Ideal for small fuel storage and transfer.

• Service Stations (Auxiliary Metering): Used for auxiliary fuel dispensing equipment.

• Agricultural Machinery Stations: Provides fuel transfer and metering for agricultural machinery.

• Industrial Plants: Suitable for internal fuel transfer and management.

• Vehicle Fleets, Ships, and Ground Equipment at Airports: Supports fuel transfer and metering.

This pump is especially suitable for mobile, intermittent, and on-site fuel handling operations.
