SF-type single-stage double-suction corrosion-resistant split-case pump structural design
SF-type corrosion-resistant Double-suction pump For horizontal installation, both the suction and discharge ports are located below the pump shaft centerline. The pump casing features a horizontal split design, allowing maintenance without the need to disconnect the inlet and outlet pipelines. The shaft seal is a soft packing seal; it can also be replaced with a mechanical seal.
Rotation Direction: When viewed from the motor end toward the pump, the SF-type corrosion-resistant double-suction split-case pump rotates counterclockwise; in this case, the suction port is on the left and the discharge port is on the right. The split-case centrifugal pump rotates clockwise; in this case, the suction port is on the right and the discharge port is on the left.
Package scope: The package includes a split-case pump, motor, baseplate, coupling, and inlet and outlet short pipes.

Q
What is your typical delivery time?
A
Models in stock can be shipped the next day at the latest. All others are custom-made, with lead times generally ranging from 7 to 90 days depending on the product size and project specifics. Please contact our sales manager for details: 0731-88632200 。
Q
Do you have centrifugal pumps in stock?
A
Centrifugal pumps come in numerous models and configurations. Except for a small number of high-volume, standard models that are in stock, the vast majority are not stocked and are customized products. We need to select a pump based on your site's flow rate, head, media temperature, pH value, and installation conditions, etc., to determine the pump model and configuration before we can submit an order to the factory for production.
Q
What information should I provide when requesting a quote?
A
Generally, to obtain an accurate quotation, we recommend providing us with the following information: pump flow rate, head, on-site operating voltage and frequency, temperature, pH value, and solid particle content of the fluid being conveyed, and on-site installation conditions (horizontal or vertical installation), etc.
If you are not sure, don't worry, our business managers will assist you in determining this.
Q
What products do you mainly produce?
A
Zhonglian Pump Industry manufactures various large industrial centrifugal pumps. Main products include: self-balancing multi-stage pumps, multi-stage centrifugal pumps, single-stage centrifugal pumps, split-case pumps, chemical pumps, submersible pumps, pipeline pumps, long-shaft pumps, condensate pumps, etc.
Q
Why is it so slow to get a price quote?
A
Because centrifugal pumps are non-standard customized products with many models, the price range is also very large. Even for the same model, the price difference is also very large due to different materials and configurations. Taking the most common water pump accessory—the impeller—as an example, the price of a stainless steel impeller is several times that of a cast iron impeller. Therefore, we need to clarify the relevant information to give you an accurate price. Normally, if you provide relatively comprehensive information, we can quote within 5 minutes.
