[Three rain valve to recommend star products - mechanical seals] Description: self-priming sewage pump mechanical seal with anticorrosive hard tungsten carbide material QY8.4-50-3 pump, but will also improve the double-end sealing seals for long in the oil chamber, can pump more than 8000 hours continuous operation safety. Self-priming non-clogging sewage pump overall structure is compact, small size, low noise, energy-saving effect is remarkable, easy maintenance, no need to build pumping stations, the self-priming pump sewage into the water to work QY100-4.5-2.2 pump, greatly reducing the project cost . Self-priming sewage pump seal oil chamber with high precision interference leakage detection sensor, and the stator windings of the thermal components embedded, absolute protection of pump motor. Performance parameters: Flow: 6-800m3 / h; Head: 14m-80m; ambient temperature ≤50 ℃, medium temperature ≤80 ℃; severe media not more than 1050 kg / m3; the total length of the suction pipe ≤10m; by the ability of suspended particles in diameter 10% of the pump diameter, fiber length is five times the diameter of the pump. [Three rain valve to recommend Star Products - Mechanical seal] Description: submersible sewage pump is a pump and motor piece, and also sneak into the sump pumps work, and generally horizontal or vertical pump sewage pump Compared pumps, sewage pumps clearly has the following advantages: 1, compact structure, small footprint. Due to sneak under the liquid sewage pump work, it can be directly installed in the sewage tanks, without the construction of pumping station dedicated to install the pump and machine, you can save a lot of land and infrastructure costs. 2, easy installation and maintenance. Small sewage pumps can be installed free, large sewage pumps are generally equipped with automatic coupling device can be automatically installed, installation and maintenance very easy. QY15-26-2.2 pumps, water pumps selected three rain (certified), Xinyang pumps supplied by Valve Co., Ltd. Tianjin three rain. Valve Co., Ltd. of Tianjin, rain (www.tjsymf.com) (www.tjsymf.com) is a leader in Tianjin, seals, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Three rain valve leadership with the staff warmly welcome all inquiries negotiations to create three rain valve better future.
