3.2GPM Gear Pump 12V Self-Priming Oil Transfer – Yenergy GP-3.2-12

Description

Product Overview

The Yenergy 3.2GPM Gear Pump (model GP-3.2-12) is a high‑performance, 12‑volt, self‑priming pump designed for the transfer of lubricants, viscous liquids, and diesel engine fuel. Built around a robust bronze shaft and a fully enclosed stainless‑steel housing, the pump delivers a maximum flow of 3.2 gallons per minute while maintaining a compact footprint of 8.46 x 5.31 x 4.33 inches and a weight of just 5.91 pounds. The impeller is crafted from a premium neoprene compound, providing excellent chemical resistance and long‑term durability even when handling aggressive fluids.

Key technical specifications include a 12VDC power requirement, a maximum head of 3 meters, and an amp draw not exceeding 10 A. The motor utilizes a permanent‑magnet design for efficient power conversion and reduced heat generation. Ports feature a 3/8″ female thread and 1/2″ barbed fittings, allowing flexible installation in a variety of system configurations. The pump’s seal is a lip‑type design, ensuring a tight, leak‑free operation under continuous load.

Yenergy’s commitment to quality is evident in the pump’s fully enclosed stainless‑steel construction, which protects internal components from dust, moisture, and corrosive environments. The built‑in thermal protection system monitors motor temperature and automatically shuts down the pump if overheating is detected, safeguarding both the equipment and the operator. This combination of material excellence, precise engineering, and safety features makes the GP‑3.2‑12 a reliable choice for demanding industrial applications.

Usage

Designed for versatility, the Yenergy 3.2GPM Gear Pump excels in a wide range of industrial and scientific settings. It is ideal for lubricating heavy machinery, circulating oil in hydraulic systems, and extracting fuel from diesel engines for scavenging or testing purposes. The self‑priming capability allows the pump to start drawing fluid from a depth of up to 3 meters without manual priming, reducing setup time and minimizing the risk of air entrapment.

In manufacturing plants, the pump can be integrated into cooling‑oil loops, ensuring consistent temperature control for high‑speed spindles and cutting tools. Its compact size and lightweight design enable easy mounting on mobile platforms, making it suitable for field service technicians who need to transport equipment between job sites. The 12‑volt power requirement aligns with standard automotive and marine battery systems, allowing the pump to operate in remote locations where conventional AC power is unavailable.

For marine applications, the pump’s corrosion‑resistant stainless‑steel housing protects against saltwater exposure, while the bronze shaft tolerates the abrasive nature of marine fuels. In laboratory environments, the precise flow rate and low pulsation output provide accurate dosing for experimental setups that require consistent fluid delivery. Overall, the pump’s adaptability, combined with its robust construction, makes it a valuable asset for any operation that demands reliable fluid transfer.

FAQ

What fluids can the pump handle?

The pump is rated for lubricants, viscous oils, and diesel fuel. Its neoprene impeller and stainless‑steel construction allow it to safely transfer a wide range of industrial fluids without degradation.

How does the self‑priming feature work?

When the pump is powered, the impeller creates a vacuum that draws fluid up through the inlet port. This process can lift fluid from a source up to 3 meters below the pump, eliminating the need for manual priming.

Is the pump suitable for continuous operation?

Yes. The built‑in thermal protection monitors motor temperature and shuts down the pump if it exceeds safe limits, allowing for long‑duration use without overheating.

Can the pump be powered by a standard car battery?

Absolutely. The 12 VDC rating matches typical automotive and marine batteries, making it ideal for portable or off‑grid applications.

What maintenance is required?

Periodic inspection of the inlet and outlet fittings for wear, as well as checking the motor for any signs of overheating, is recommended. The pump’s sealed design minimizes routine maintenance, but keeping the external housing clean will ensure optimal performance.
