VEVOR Air Operated Double Diaphragm Pump 158 GPM 2″ Inlet/Outlet

Description

Product Overview

The VEVOR Air Operated Double Diaphragm Pump is engineered for high-volume fluid transfer in demanding industrial environments. Constructed from a solid aluminum alloy body, the pump resists corrosion, wear, and impact, extending service life even under continuous operation. Triple-layer rubber diaphragms provide a sealed, leak‑proof chamber that tolerates abrasive liquids and high pressures up to 114 psi. With a maximum flow rate of 158 gallons per minute, the pump moves large volumes quickly, reducing downtime and labor costs. Standard 2‑inch inlet and outlet ports match common piping, allowing seamless integration into existing pneumatic systems without custom adapters. The pump operates solely on compressed air, eliminating the need for electrical power and reducing fire risk in hazardous locations. Its full‑bolt construction and reinforced mounting points ensure stability on the shop floor, while the compact footprint (17.72 x 13.78 x 27.56 in) fits into tight spaces.

Usage

This pneumatic transfer pump excels in a variety of applications. In automotive workshops, it quickly drains waste oil from engines, transmissions, and gearboxes, allowing technicians to recycle or dispose of fluids responsibly. In manufacturing plants, the pump handles hydraulic oil, diesel, gasoline, and even non‑corrosive chemicals, moving them from storage tanks to processing units with minimal spillage. Water‑treatment facilities use the pump to relocate lubricating oils and cleaning solvents, while metal‑working shops rely on its ability to transfer viscous paints and coatings without clogging. The pump’s air‑only operation makes it safe for use in explosive atmospheres, such as fuel depots or paint booths, where electrical devices could ignite vapors. Its robust design also supports field service crews who need a portable, reliable solution for on‑site fluid relocation, such as emptying fuel drums or cleaning oil‑filled equipment.

Why Choose Us

Choosing the VEVOR pneumatic diaphragm pump means investing in durability, efficiency, and peace of mind. The aluminum alloy housing is machined to tight tolerances, delivering a rigid structure that resists deformation under high pressure. Triple‑layer rubber diaphragms are selected for their chemical resistance and elasticity, guaranteeing a leak‑free seal even after thousands of cycles. Because the pump is air‑operated, it eliminates the need for electrical wiring, reducing installation complexity and maintenance costs. VEVOR provides a comprehensive warranty and responsive technical support, ensuring that any questions about installation, operation, or troubleshooting are answered promptly. Our after‑sales service includes spare part availability and detailed user manuals, helping customers keep the pump running at peak performance for years.

FAQ

What types of liquids can this pump handle?

The pump is designed for non‑corrosive liquids such as waste oil, diesel, gasoline, hydraulic oil, detergents, and certain beverages. It should not be used with strong acids, alkalis, or liquids above 140 °F.

Do I need any special equipment to operate the pump?

Only a source of clean, dry compressed air (typically 90‑120 psi) is required. No electrical power or additional pumps are needed, making it ideal for remote or hazardous locations.

How do I maintain the diaphragms for long service life?

Regularly inspect the diaphragms for wear or cracks and replace them according to the maintenance schedule in the user manual. Keep the pump clean and free of debris to prevent abrasion.

Can the pump be used outdoors?

Yes, the aluminum alloy construction and sealed diaphragms allow outdoor operation, provided the ambient temperature stays below the recommended maximum and the air supply is protected from moisture.

What is the warranty period for this pump?

VEVOR offers a one‑year limited warranty covering manufacturing defects, along with access to technical support for installation and troubleshooting.
