Industrial pressure boosting: Water system,cleaning system,high pressure washing system and firefighting system
Field irrigation(flooding), Sprinkler irrigation, Drip-feed irrigation
Features
1. Identify noise sources : Gain a comprehensive understanding of the different components and operations of the pump that contribute to noise generation. These components may include the motor, impeller, bearings, housing, and fluid flow.
2. Analyze the operating conditions : Thoroughly assess the pump's operating parameters, such as flow rate, pressure, temperature, and fluid properties. These factors can significantly impact noise levels and provide valuable guidance during the design process.
3. Implement noise reduction techniques : Employ a range of effective noise reduction strategies to specifically target and mitigate the identified sources of noise.
4. Maintenance and regular inspections : Ensure proper maintenance of the pump by regularly inspecting for worn-out or damaged parts that can contribute to increased noise levels. Promptly address any identified issues to maintain optimal performance.

A:The sample can be sent to customer within 7-12 days. The batch order can be shipped within 35 days after receiving deposit payment.
Q:Where is your
loading port?
A: Ningbo port, China
Q: Can you accept c
ustomized products?
A: Yes we accept your specific order.
Q: What is your
payment term?
A: 30% in advance, 70% balance the B/L or T/T.
Q: What is the
warranty of the product?
A: We offer 1 year product life guarantee.
Q: What
information shall I provide you when I need your offer?
A: Pump flow, total head, pump material (copper wire or aluminum wire? Stator length), voltage, frequency, etc.
Q: Will you supply any
spare parts with the pumps?
A: Yes,Like tank, flexible hose, pressure switch, pressure gauge, brass connector, cable, etc.
Q: Is there any
leakage problem of this pump?
A: Some factory may have such problem, but we solved it very well, by using good material of pump casing, O-ring, and they fit each other perfect. We use 8 screw on the pump head while others may use only 6 screw to save cost. We test 100% and long time for the pump head part, to make sure there is no leakage problem.
Q: Where did you
export to?
A: We export to more than 50 countries, for example, Israel, South Africa, Germany, Poland, Spain, Vietnam, Malaysia, Russia, Thailand, Mexico, Brazil, Chile, etc.
Q: Can I order some
accessories with the pump?
A: pressure tank, flexible hose, 5-way connector, pressure gauge, pressure controller and assemble
Q: Can the pump be made by customized
voltage and frequency?
A: Yes, 220-240V, 110V, 50Hz, 60Hz,,all OK!
