Q - My application requires an opening flow/pressure that is not listed on your charts, would it be possible to get a custom spring?
A - Yes, we do design custom springs for special applications.
Q - Can I buy one pump directly from SOVOFLO?
A - SOVOFLO Micro Pumps builds to order for the Original Equipment Market. Generally, the customer can purchase from the factory directly, or You may also purchase a pump from our online store:
https://www.aliexpress.com/store/1100489247. We support payment via T/T, Credit Card, Western Union, Alipay and Paypal etc.
Q - Why is it necessary to know the size and length of tubing the pump will be connected to?
A - Long or restrictive tubing causes high pressure drags. This will reduce the pump flow and/or require more power.
Q - Which pumps can I run dry?
A - Diaphragm pumps, piston pumps and peristaltic pumps can be run dry for any length of time. Centrifugal, rotary vane, and gear pumps should not be run dry; exceptions are if the gear or impeller is made of a self-lubricating material such as RYTON in which case the pump can be run for a few minutes while priming.
Q - What is the maximum viscosity rating for pumps?
A - This depends on the type of pump and the specific pump. Diaphragm pumps (especially double diaphragm pumps) and gear pumps are usually the best for viscous fluids.
Q - What about quality assurance?
A - We offer one warrantee period beginning from the time of shipment for OEM application, we can provide spare parts for replacements, if our serious product problems, we can make replacement of free charge.
Q - What about the price level?
A - We are confident that our prices are competitive compared with those at the same quality level, since we have stayed in this filed more than 14 years. And we always adhere to the principle of provide top quality products with competitive prices.
Q - Why we find some prices are very high compared with some other supplier, and from the picture or it's parameter, all looks the same?
A - As China is still a developing country, there are only a few products with patent rights, and copy products l spread very fast in the market. Of course, the prices of those copy products with cheap material and less quality control are relatively cheaper.
Q - WHAT IS AN EXTERNAL GEAR PUMP?
A - An external gear pump is a volumetric pump that has two gears meshing with each other in a close-fitting housing. As the gears rotate, fluid fills the space between corresponding gear teeth and is carried from the inlet side to the outlet around the external circumference of the gears. Where the teeth mesh together, fluid cannot pass and so it is ejected through the outlet.
Q - WHAT CONSIDERATIONS SHOULD BE MADE FOR PUMP INSTALLATIONS?
A - It is good practice to keep inlet lines as short and restriction free as possible, so ideally mount the pump under the reservoir. The pump can prime if mounted above the reservoir but this is less efficient and special priming procedures may be required. An appropriately sized filter should be fitted in the inlet flow path. Isolation valves installed on either side of the pump may make servicing cleaner/simpler where tanks are not drained regularly.
Q - WHAT CHEMICALS CAN BE PUMPED?
A - Our pumps are manufactured in a range of materials and it is possible to find a compatible material for most fluids. In any case given the variety of conditions and fluids it is always advisable testing the pump in the circuit, under conditions and with the fluid which will then be in operation.
Q - CAN THE PUMPS BE USED FOR METERING?
A - All of our pumps are positive displacement units and can be used in metering applications. Accuracy and repeatability will be dependent on the pump type used, the drive/control system, and the fluid. Please contact us for further information.
Q - WHAT DRIVES ARE AVAILABLE?
A - We offer a range of different drive types including DC, Brushless DC, Integrated, AC and Stepper motors. Air driven motors are also availbale on some models.
Q - WHAT SHOULD BE CONSIDERED WHEN DESIGNING A PIPING SYSTEM FOR PUMPS?
A - Keep suction requirements to a minimum, bends are better than elbows. Keep the tank high and the pump low. Use appropriately sized piping or tubing. Use isolation dampeners to avoid vibration induced noise. Design a filter before the pump and maitain it clean.
