FAQ:
Q1: How do I choose between the KBZ and KBS series for my project?
A: The choice depends on the sediment content of your water. The KBZ series is designed for high-pressure discharge of relatively clean or sandy water, making it perfect for general construction dewatering. If you are dealing with thick mud, sludge, or water with heavy sediment, the KBS series is the better choice as it features a built-in agitator to suspend solids before pumping.
Q2: What materials are used to ensure the pump’s durability in abrasive environments?
A: At Tussu Pump, we use high-chromium alloy (Hi-Cr) for our impellers and wear plates. This material is significantly harder than standard cast iron, providing excellent resistance against sand and grit erosion, which extends the pump’s service life in mining and tunneling.
Q3: Can these pumps run continuously if the water level is low?
A: Yes. Our pumps are designed with a top-discharge, side-flow path or a water jacket. This allows the pumped liquid to cool the motor even when the pump is only partially submerged, preventing overheating during long-term operation.
Q4: Do you offer stainless steel options for corrosive wastewater?
A: Absolutely. While our standard dewatering pumps are heavy-duty cast iron, we provide Stainless Steel Submersible Sewage Pumps (SS304/SS316) for applications involving acidic or corrosive industrial effluents. Please contact our team for a material compatibility consultation.
Q5: What is the maximum solid handling size for Tussu dewatering pumps?
A: The solid-to-liquid ratio and particle size vary by model. Generally, our industrial series can handle spherical solids ranging from 8mm to 25mm. For larger debris or fibrous materials, we recommend our sewage pump series with cutter mechanisms.
Q6: How often should the mechanical seals be inspected?
A: For heavy-duty industrial use, we recommend a routine inspection every 2,000 to 3,000 hours. Tussu pumps utilize dual mechanical seals in an oil chamber, which provides superior protection. Regular oil checks can prevent motor failure and significantly reduce maintenance costs.
