The GLB series self-priming pump is a new type of high-efficiency and energy-saving premium product with internationally advanced level. It is optimized and upgraded on the basis of ordinary self-priming pumps, and newly developed with an added intelligent automatic control device.
During operation, the pump can quickly separate the gas precipitated from the suction pipeline or the conveyed medium from the liquid medium, and discharge the gas rapidly from the pump volute. Under the control of the intelligent device, the pump delivers water immediately after startup, realizing synchronous exhaust and water discharge.
The inlet and outlet flow passages of the GLB series self-priming pump adopt a no-bend flow channel design, which effectively minimizes flow resistance and energy loss during medium transportation.With the impeller and volute designed by a special hydraulic model and manufactured with advanced production technology, the pump efficiency is increased by 20%–30% compared with ordinary self-priming pumps, delivering remarkable energy-saving effect.
The GLB high-efficiency energy-saving self-priming pump is equipped with a dedicated vertical VI motor, fitted with high-quality imported bearings such as SKF and NSK. Grease nipples are arranged on both front and rear end covers. It features stable operation, high precision, low noise and long service life.
The impeller, volute and pump shaft of the GLB pump are cast and machined from special wear‑resistant stainless alloy materials. A easily detachable wear-resistant alloy wear ring is installed at the matching position between impeller and volute. When the operating efficiency declines, only replacing the wear ring can restore the pump to its factory-rated performance parameters. It not only reduces maintenance cost, but also achieves a service life 5–8 times that of long-shaft submerged pumps, vertical long-shaft pumps and submersible sewage pumps under normal working conditions.
The GLB series adopts two types of cartridge mechanical seals: water-cooled type and self-cooled type.For conveying normal-temperature particle-free media, the cartridge self-cooled mechanical seal is optional, which is durable and requires no cooling water supply.For harsh working conditions with high temperature and solid particles such as iron oxide scale and sand grains in sewage, the cartridge water-cooled mechanical seal is adopted. The sewage medium does not contact the seal faces, keeping the mechanical seal in good operating condition permanently and ensuring long-term durable operation of the pump unit.
The GLB pump is designed with an intelligent vacuum pumping device. No priming water is required; normal water delivery can be achieved within 0–15 seconds after startup. An automatic control system can be equipped upon customer request, enabling automatic start at high liquid level and automatic stop at low liquid level on site or remotely, realizing unattended safe and reliable operation.
The GLB pump adopts a vertical derrick-type fixed structure, featuring compact layout, small floor area and low lifting height. It requires no large pump house or heavy lifting equipment for installation, with simple, convenient and low-cost operation and maintenance. According to the space layout and actual demand of the pump house, the suction inlet can be designed at any axial position to meet various working condition requirements.
