▼Product introduction

The F-type stainless steel direct-coupled centrifugal pump is made of high-quality stainless steel, featuring a compact structure and strong corrosion resistance. Its direct-coupled design ensures stable operation and easy maintenance.

▼Application environment

Wide range of industry applications ：  Used extensively in chemical, electroplating, wastewater treatment, food and beverage, pharmaceutical, and fine chemical industries.

▼Product features and advantages

1.Corrosion-resistant material: Made of 304/316/316L stainless steel, resistant to acid and alkali corrosion with pH 2-13, suitable for various corrosive media.

2.Compact structure: Direct-drive design between motor and pump saves space, ensures smooth and vibration-free operation, and low noise.

3.High efficiency and energy saving: The impeller is optimized for fluid dynamics, resulting in high hydraulic efficiency and saving 15%-20% more energy than traditional pumps.

4.Reliable sealing: Equipped with a high-quality mechanical seal, leak-free, long service life, and adaptable to various operating conditions.

5.Wide application: Can handle liquids containing fine impurities, suitable for chemical, food, pharmaceutical, and wastewater treatment industries.

▼Working principle

When the pump starts, the liquid stored in the pump is thrown upwards by the impeller, carrying air with it. The liquid flows back to the working chamber through the gas-liquid separation chamber, and the gas is discharged outside the pump, creating a certain degree of vacuum inside the pump and achieving self-priming.

▼Shopping and maintenance suggestions

1. Selection of Suitable Materials ：  Choose 304/316/316L material based on the corrosiveness of the medium, matching flow rate, head, and operating conditions. For media temperatures exceeding 80℃, select a high-temperature seal; for media containing particles, select a semi-open impeller; for explosion-proof environments, use an explosion-proof motor.

2. Proper Installation ：  The suction pipe must be airtight. The installation height should not exceed the pump's self-priming limit. Minimize bends and excessively long pipelines to avoid cavitation affecting operation.

3. Routine Maintenance ：  Regularly inspect the mechanical seal and bearings, and clean impurities from the filter. After shutdown, drain the liquid from the pump to prevent freezing and cracking. For long-term inactivity, perform rust prevention maintenance to extend service life.

▼Precautions for use

1. Before startup ：  Fill the pump with liquid and purge all air to prevent dry running and damage to the seals; check the suction pipe seal for leaks, confirm the motor rotation direction is correct, and ensure the medium temperature and viscosity are within the pump's operating range.

2. During operation ：  Monitor pressure and flow for stability, avoiding operation beyond rated conditions; if abnormal noise, vibration, or leakage occurs, immediately stop the pump and investigate to prevent cavitation or component wear.

3. After shutdown ：  In low-temperature environments, drain the liquid from the pump to prevent freezing and cracking; regularly clean the filter for impurities, check the mechanical seal and bearing condition, and perform rust prevention maintenance for long-term inactivity.
