It delivers a max flow rate of 18 liters per minute with a 3/8" fluid inlet and 1/4" air inlet, operating efficiently up to 7 bar pressure. Designed for chemical industrial use, it offers low noise, vibration, and smart self-protection to prevent damage, making it a reliable choice for professionals seeking durable, easy-to-maintain pumping solutions. ## Description Product Parameters :Model: A-15Fluid input size: 3/8 inchAir input size: 1/4” NPTMax pressure: 7bar Max pressure amoint: 18L/min Max pump speed: 500cpm ## Features - Superior Quality and Performance: Pneumatic diaphragm pumps feature reliable quality, long service life, low noise, low vibration, never crashing, and fine workmanship. They can pump flowing liquids and transport some difficult-to-flow media. - Easy Operation and Self-Protection: Easy to use and reliable in work, only needs to open and close the gas valve. Even if the pump runs without medium for a long time due to unexpected circumstances or suddenly stops, it will not be damaged. Once overloaded, the pump will automatically stop with self-protection performance, and when the load returns to normal, it can automatically start operation. - Simple Maintenance Design: This diaphragm pump has simple structure, few wearing parts, convenient installation and maintenance. The medium conveyed by the pump will not touch the moving parts such as the valve, linkage, etc., unlike other types of pumps due to the wear of rotors, pistons, gears, blades and other parts. - Chemical Compatibility Notice: This diaphragm pump can be used to pump chemical liquids, and the diaphragm used is PTFE acid and alkali corrosion resistant diaphragm. However, because the pump is aluminum alloy, it is best not to pump strong acid and alkali substances that will react with aluminum alloy. - Operating Pressure Requirements: The pump cannot be used when empty, as running without liquid inside for a long time will cause bursting. The optimal air pressure is 4 kilograms with a maximum of 6 kilograms, exceeding this pressure will damage the diaphragm pump ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B097DFY7GV | | Best Sellers Rank | #294,265 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #146 in Diaphragm Pumps | | Brand Name | MXBAOHENG | | Color | Silver | | Customer Reviews | 4.0 4.0 out of 5 stars (15) | | Flow Rate | 18 Liters Per Minute | | Included Components | Pneumatic Diaphragm Pump | | Item Weight | 3 Pounds | | Manufacturer | MXBAOHENG | | Manufacturer Part Number | HQ-2588 | | Material Type | Aluminum | | Model Number | HQ-2588 | | Power Source | Air Powered | | Product Style | Diaphragm Pump | | UPC | 885946489764 | ## Product Details - **Brand:** MXBAOHENG - **Color:** Silver - **Item Weight:** 3 Pounds - **Manufacturer:** MXBAOHENG - **Material:** Aluminum - **Maximum Flow Rate:** 18 Liters Per Minute - **Number of Items:** 1 - **Number of Packs:** 1 - **Power Source:** Air Powered - **Style:** Diaphragm Pump ## Images ![MXBAOHENG Air-Operated Diaphragm Pump Pneumatic Double Diaphragm Transfer Pump 3/8" Inlet & Outlet 1/4" Air Inlet for Chemical Industrial Use (18L/min) - Image 1](https://m.media-amazon.com/images/I/714B1qgABeS.jpg) ![MXBAOHENG Air-Operated Diaphragm Pump Pneumatic Double Diaphragm Transfer Pump 3/8" Inlet & Outlet 1/4" Air Inlet for Chemical Industrial Use (18L/min) - Image 2](https://m.media-amazon.com/images/I/61YP3jPsVFS.jpg) ![MXBAOHENG Air-Operated Diaphragm Pump Pneumatic Double Diaphragm Transfer Pump 3/8" Inlet & Outlet 1/4" Air Inlet for Chemical Industrial Use (18L/min) - Image 3](https://m.media-amazon.com/images/I/71W-EazW86S.jpg) ![MXBAOHENG Air-Operated Diaphragm Pump Pneumatic Double Diaphragm Transfer Pump 3/8" Inlet & Outlet 1/4" Air Inlet for Chemical Industrial Use (18L/min) - Image 4](https://m.media-amazon.com/images/I/71aiq8+W2kS.jpg) ![MXBAOHENG Air-Operated Diaphragm Pump Pneumatic Double Diaphragm Transfer Pump 3/8" Inlet & Outlet 1/4" Air Inlet for Chemical Industrial Use (18L/min) - Image 5](https://m.media-amazon.com/images/I/81CVrB2IxnS.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Would this pump work for a 15% sodium hydroxide or lye in water solution, pH 10?** A: Yes. ## Frequently Bought Together - MXBAOHENG Air-Operated Diaphragm Pump Pneumatic Double Diaphragm Pump 3/8" Inlet & Outlet Transfer Pump 1/4" Air Inlet for Chemical Industrial Use (18L/min) - TAILONZ PNEUMATIC 1/4"NPT Solenoid Valve 4V210-08 AC110V Single Coil Pilot-Operated Electric 2 Position 5 Way Connection Type Junction Box - TAILONZ PNEUMATIC Male Straight 1/4 Inch Tube OD x 1/8 Inch NPT Thread Push to Connect Fittings PC-1/4-N1 (Pack of 10) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/360881575-mxbaoheng-air-operated-diaphragm-pump-pneumatic-double-diaphragm-transfer-pump](https://www.desertcart.us/products/360881575-mxbaoheng-air-operated-diaphragm-pump-pneumatic-double-diaphragm-transfer-pump) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-04*
