Packed Safely in Bubble Bag Cautioned: the battery model without protective plate, so strongly recommend using standard high-quality constant current constant voltage function special balance charge charge using a simple charge friends please note: to safety, remember to charging in care, full immediately cut off the power supply.Charging constant current current is not more than 1C, constant voltage not more than 4.2V/, conditions allow suggested by about 0.5c current charging 1C discharge voltage can not be lower than 2.8V/, high rate discharge voltage can not be lower than the 3.3V/. Lithium batteries due to overcharge, over discharge will cause the battery to swell, and can not be repaired, so charge must be in custody, full should disconnect the power supply in time discharge should be in charge discharge depth, best equipped with a low-pressure alarm device to prevent over discharge. We are not responsible for the swollen cell replacement and repair, please buyers must pay attention to.
When charging the battery must pay attention to safety, away from combustible items, charging as much as possible in the vicinity of the work, such as long time (more than the full power of time) to stop charging, come back and then charge.
Do not easily modified battery, the former must be modified to contact the customer service staff to confirm, or by the factory's technical staff to be modified and then shipped. We will not be responsible for the replacement and maintenance of the battery if it does not change the battery.

Electric core capacity: 300mAh
Nominal voltage: 3.7V
Discharge rate: 30C/50C
Plug line: JST plug, 24# silicone wire
Product weight: 6.4gThis product is mainly used for micro electronic products and toys on the aircraft model, micro model, large current discharge etc..Take the goods, please note that the direction of the plug and the positive and negative polarity is correct, remember!keep in storage In order to ensure the battery to maintain the capacity level, the proposed battery and battery pack-20~35CStorage, low humidity, non corrosive gas conditions Battery to avoid the high temperature or high humidity storage, otherwise it will lead to battery leakage, rust, and low capacity. Long term storage will likely lead to a reduction in the capacity of the battery and battery pack, and the need for1-3A charge/Discharge cycle to achieve maximum discharge capacity. The battery should be charged and discharged once in three months. Warning: Reverse charge is not allowed, the battery should be connected according to polarity accurately, and can not be reversed. Short circuit is not allowed, otherwise it will result in permanent damage. The battery can not be used in the limit conditions, such as: limit temperature, deep cycle, extreme over charging and over discharge. Store the battery in a cool, dry place. If a large number of batteries are stored or shipped, the battery must be put in place first. Do not directly to the battery solder. If the battery appears noise, high temperature, leakage and other abnormal situation, please immediately stop using. Do not put into fire or try to disassemble the battery. The battery may burn or produce harmful substances. It is not permitted to use old batteries or use half of the battery with the new battery, otherwise it will have a discharge. Outer casing and outer jacket tube for removing the battery. The battery is not allowed to be put in the water. Matters needing attention: Battery should be fully charged before use. The charging method according to technical specifications of our. Charge using the corresponding charger. The battery should avoid the use of sealed, should provide the appropriate ventilation device, otherwise the battery may produce hydrogen, in the case of ignition point will cause the explosion. Don't attempt to battery separation or bear extrusion and collision may lead to battery fever, furious, spilled alkaline electrolyte will damage skin and eyes corrodes the clothes. The battery should be kept away from the child, if swallowed, immediately contact the doctor to deal with. When the battery is not in use, it should be removed from the device. When the first use of a new battery or long-term storage use, before the need to be filled with electricity. When the battery is hot, do not touch it until it cools down. When the battery is used, it is found that the energy should be turned off when the energy is decreased, so as to avoid over discharge. When you pull out the battery, you should hold the battery pack and not hold the wire. After the battery is used, if the battery is hot, it can be put in a place where there is no direct sunlight to cool down before charging again.

Stationary wear parts consist of the front casing rings and back bushing rings. Stationary wear parts are shrunk and pinned (axial grub screws) in the casing to prevent rotation. API 610 10th edition clearances are standard on the front ring with Flowserve standard clearances on the back bushing ring.
Multi vane diffuser/ channel ring inter stage assemblies are used to balance radial loads throughout the pumps operating range. Low radius diffuser vanes ensure the shock – less transition of the fluid from impeller outlet to the impeller eye of the next stage, minimizing efficiency loss and undesirable pulsations. A metal to metal inter-stage fit prevents internal leakage and subsequent loss of performance. Designed for the optimum D5/D2 ratio to match the impeller specific speed, the compact design minimizes the barrel internal diameter and hence the overall size and weight of the pump.
This product is provided with a balance device that balances the pressure between the inboard and outboard seal chambers and controls the axial thrust. The balance device is available as a straight drum design or a flanged drum (clean liquids e.g boiler feed). In both instances the sleeve component is shrunk onto the shaft with a keyed drive whilst bushings are pinned in the casing to prevent rotation. Both drum and flanged drum options have a serrated surface on rotating axial pressure breakdown component with Flowserve standard clearance, API clearance can be applied with a reduction of efficiency.
This pump is available with Ball/Ball, Sleeve/Ball and Sleeve radial/ Sleeve-tilting pad bearings. The choice of bearing configuration will depend upon the operating speed, shaft power and type of balancing device used. When a tilting pad thrust bearing is required the arrangement of choice will be a self-contained arrangement to avoid the use of a separate force feed lube oil system.
Bearing housings and end covers are supplied in carbon steel only. Provision is made for temperature detectors for measuring bearing metal temperature and housings are dimpled for taking vibration readings. When sleeve type journal bearings are used bearing housings will have provision for radial proximity probes.
All bearing housing are fitted with a bronze labyrinth flingers to prevent oil leakage and the ingress of foreign materials to the bearings.
To permit thermal growth of the pump on the bedplate when used on hot applications, the pump will be pinned at the coupling end allowing axial movement at the non-drive end.
Base-plates are reinforced, welded-steel, drain-rim type, common to both the pump and driver, standard construction is a grouted design, alternative non-grouted designs are available to suit offshore applications.
