SYL Vertical Centrifugal Pump

I. Product Overview

The SYL series single-stage, single-suction vertical centrifugal pump is an energy-efficient product designed and manufactured by combining the structural characteristics of vertical pumps with the performance parameters of the IS series centrifugal pump.

Designed and manufactured in strict accordance with ISO 2858 international standards and relevant national standards, this product serves as a replacement for conventional pumps such as the IS series horizontal centrifugal pump and the DL series pump.

The product offers a flow rate range of 1.5–2400 m³/h and a head range of 8–150 m, featuring various specifications and models, including basic types, expanded-flow types, and A/B/C impeller-trimmed types.

Depending on the conveyed medium and operating temperature, the product line can be extended to include the following series:

- SYR series vertical hot water pump

- SYH series vertical chemical pump

- SYY (YG) series vertical oil pump

- SYHY series vertical explosion-proof chemical pump

These products are widely used in industrial water supply and drainage, HVAC circulation, fire-fighting pressure boosting, chemical fluid transport, and equipment integration.

II. Product Features

1. Compact Structure

The product features a vertical design, resulting in a small footprint and an aesthetically pleasing appearance.

The pump's center of gravity aligns with the installation center, enhancing operational stability and extending the equipment's service life.

2. Easy Installation

The inlet and outlet diameters are identical and aligned on the same centerline, allowing for direct installation into piping systems.

Certain models can be equipped with rain covers for outdoor installation.

3. Stable Operation

The motor utilizes low-noise bearings, and the impeller undergoes dynamic and static balancing; this results in minimal vibration and low noise, improving the on-site operating environment.

4. Reliable Sealing

The shaft seal employs a wear-resistant hard alloy mechanical seal, effectively reducing leakage and extending the equipment's service life.

5. Convenient Maintenance

Maintenance can be performed without dismantling the piping; simply removing the pump cover nuts allows access to the motor and drive components.

6. Flexible Installation

Installation methods—such as vertical or horizontal configurations—can be selected based on site conditions.

Additionally, pumps can be operated in series or parallel to meet specific flow and head requirements.

III. Scope of Application

1. System Pressure Requirements

The maximum working pressure of the pump system is ≤1.6 MPa. That is: Pump suction inlet pressure + Pump head ≤ 1.6 MPa.

If the inlet pressure exceeds 0.4 MPa or the system operating pressure exceeds 1.6 MPa, please specify this when ordering so that high-strength materials (such as cast steel) can be used for relevant components.

2. Requirements for pumped media

"Clear water" type products are suitable for transporting non-corrosive liquids.

The volumetric content of insoluble solids in the medium must not exceed 0.1%, and particle size must be < 0.2 mm.

If the medium contains fine particles, please specify this in advance when ordering.

3. Environmental conditions

Ambient temperature: ≤ 40°C.

Relative humidity: ≤ 95%.
