Overview
The GDL vertical condensate lift pump is a new generation product designed and manufactured by our company based on excellent pump types abroad, combined with user requirements and relevant fire safety standards, and according to JB/TQ6435-92 standards. The suction and discharge ports of the water pump are located on the same straight line. The rotor components consist of shafts, impellers, impeller sleeves, shaft sleeves, and other parts. The inlet, middle, and outlet sections are connected by tension bolts. The shaft seal adopts mechanical seal and is lubricated and cooled with pressure water from the balance chamber. It is an excellent pump type for transporting cold and hot water or liquids with physical and chemical properties similar to water in various industries. All of our products are designed and optimized using computers. Our company has strong technical strength, rich production experience, and comprehensive testing methods to ensure stable and reliable product quality.

GDL vertical condensate lift pump: external installation dimension diagram
Outline installation dimension diagram:
Outline installation dimension table:
| Fault phenomenon | Possible causes | exclusion method |
| 1. The water pump is not producing water | The inlet valve is not open, the inlet and outlet pipelines are blocked, and the impeller flow channel is blocked The motor is running in the wrong direction and has a slow speed due to phase loss Leakage of suction pipe The pump is not filled with liquid and there is air inside the pump chamber Insufficient imported water supply, high suction, and bottom valve leakage Excessive pipeline resistance and improper pump selection |
Check and remove blockages Adjust the motor direction and tighten the motor wiring Tighten all sealing surfaces and eliminate air Open the pump cover or open the exhaust valve to exhaust all the air Shutdown inspection and adjustment Reduce pipeline bends and reselect pumps |
| 2. Insufficient water pump flow | First, check for reason 1 Pipeline, pump flow channel or impeller blockage, scale deposition Low voltage Impeller wear |
First, press 1 to exclude Remove the obstruction and readjust the valve opening voltage stabilization Replace the impeller |
| 3. Excessive power | Exceeding the rated flow usage High suction distance Pump bearing wear |
Adjust the flow rate and turn down the outlet valve reduce replace the bearing |
| 4. Noise vibration | Unstable pipeline support Liquid mixed with gas Generate cavitation Bearing damage Motor overload operation |
Stable pipeline Increase suction pressure and exhaust 降低真空度 replace the bearing Adjust according to 5 |
| 5. Motor overheating | Excessive traffic and overloaded operation 局部摩擦 Motor bearings damaged Insufficient voltage |
Close the outlet valve Check and exclude replace the bearing voltage stabilization |
| 6. Water pump leakage | Mechanical seal wear The pump body has sand holes or cracks Uneven sealing surface Loosening of installation bolts |
replace Welding repair or replacement trim fasten |
