New Shanghai Pump ??????????????? ordinary pump 1. Silent:? ???? Noise noisy rotor lubricated by the pumped liquid to produce: the use of mechanical seals, high speed When generating a large noise? ?????????? strong sound in less than 40 decibels, absolutely silent. ???????????????? Sound, and the use of longer noise louder 2. No leak: without mechanical seal, only two gaskets for leak outside ????:? mechanical seals, due to prolonged high-speed friction, ????????? shell static sealing, so more effective way to eliminate fluid leaks?????? dynamic and static sealing will cause water pump leakage 3. wear-resistant after High: impeller, motor consists of high temperature resistant material, not applicable ???? temperature: impeller and motor are made of conventional materials, not heat ??????????? transport temperature 2 ℃ ~ ????????????????? 110 ℃ of liquid must be fed liquid at room temperature ????? 4. Anti-wear: high hard wear-resistant ceramic bearings, bushings than graphite ?? ?? easy to wear: a metal ball bearing and mechanical seal, it will ?????????? stronger, more resistant, longer service life ?? ?????????? corrosion, wear, resulting in a vicious cycle performance 5. High efficiency: centrifugal impeller design, water, high efficiency and low efficiency:?? impeller blade design, inefficient, easy to wear ?????????? using liquid cooling no need to install the fan power consumption ?????????????? use fan cooling, additional power consumption ??? 6. Long life: a rotor and a stator made of stainless steel shielding sleeve isolated by ?? short life: head and motor separately, the motor cavity can not have liquid water into the lumen ????????? to heat, reduce insulation aging???? ?? by self-cooling and additional cooling fan mode, easy to aging Use 1, 2 solar water heating system, heating system 3, the indoor temperature hot water circulation system operating conditions 1, Power:? Voltage 230V, single-phase AC power frequency of 50 / 60Hz. All models in the sample can be manufactured according to user into voltage 230V, 60Hz frequency or voltage 115V, 60Hz frequency products, product profile and performance parameters listed in the sample only represents voltage 230V, 50Hz of frequency performance. 2, the maximum system pressure: less than 1.0MPa 3, when operating ambient temperature range: 0 ℃ ~ 40 ℃, fluid temperature + 2 ℃ ~ 110 ℃, with the exception of the pump with automatic switch (GPD-A type). Ambient temperature is always lower than the liquid temperature, or in the cavity of the stator will be condensed liquid. 4, transmission fluid: thin, clean, non-corrosive and non-explosive liquids, and do not contain any solid particles, fibers or mineral oil, pump should never be used to transport flammable liquids such as diesel and gasoline, and the like. If the circulation pump is used for higher viscosity occasion, the pump performance will be reduced, so that when selecting a pump, the viscosity of the liquid must be considered. 5, in order to avoid cavitation noise caused by damage to the shaft, maintain the following minimum pressure at the pump inlet? Liquid temperature (℃)?? 85 ?? 90 ?? 110? Head (m) ?? 0.5 ?? 3.0 ?? 10? inlet pressure (bar) ???? 0.05 ??? 0.28 ??? 1.00 245W and the following products FCL 8, 300W ~ 700W product FCL 4, 700W above products individually packaged? In order to ensure the safety of transport, to provide our customers the best order by FCL;? All products accept customer orders, are required to submit a deposit of 30%, the production period is 7-30 days;? ordered products will be shipping tax, can be opened formal invoices (17% value-added stamps)
