Section 1: Product Introduction of SPG Series Shielded Pumps

The SPG shielded pump improves the electromagnetic core technology on its original basis. It is a water pump with an integrated motor and pump body structure, featuring only stationary seals (not rotating shaft seals), thus achieving complete leak-proof performance. Due to its low noise motor, the low failure rate of the shielded pump, high reliability, and low maintenance costs, it has won the favor of a wide range of users and also increased the demand for high-quality water pumps in the Chinese market.

Section 2: Key Features of SPG Series Shielded Pumps

1. The SPG type shielded pump, due to its zero leakage guarantee, is suitable for transporting harmful and expensive liquids that are prone to leakage to both humans, the environment, and equipment.

2. Non-venting, suitable for vacuum systems and conveying liquids that deteriorate upon contact with air.

3. Oil-free seal design for reliable conveyance of high-temperature, high-pressure, low-temperature, and temperature-pressure varying fluids that are typically difficult to pump.

4. The bearings are self-lubricated with the conveying fluid, eliminating the need for additional lubricant. This ensures no contamination of the conveying fluid and eliminates the hassle of regular oiling.

5. Pump structure is rational, motor and pump are coaxial, compact in size, lightweight, takes up minimal floor space, operates smoothly, easy to install, no need for adjustment, easy to maintain, no need for adjustment, easy to maintain.

6. The impeller is designed with a hydrodynamic thrust balancing system, allowing the rotor to remain in a suspended design during operation. This reduces the轴向 wear on the graphite bearings, thereby extending the service life and lowering operating costs.

7. The motor does not have a cooling fan, resulting in very low operating noise and vibration.

8. The specification and design of the pump inlet and outlet flanges are identical to those of standard valves and are aligned on the same horizontal line, facilitating pipeline layout and making the pump room design both rational and practical.

9. High standardization and series level of parts.

10. The junction box features a waterproof design, suitable for outdoor use.

11. Pumps can be operated in series or parallel configurations according to the specific requirements of flow rate and head.

12. The newly adopted graphite bearings feature high wear resistance, low friction coefficient, non-aging, and resistance to mud and sand.

Section 3: Operating Conditions for SPG Series Shielded Pumps

1. The屏蔽泵transports media that is soft water, thin, non-caking, and free of solid particles and fibers.

2. The SPG type pump medium temperature does not exceed 90°C, while the SPG(R) type pump medium temperature does not exceed 130°C.

3. The system's inlet pressure must not be less than 0.05 MPa, ensuring the system piping is filled with liquid to allow for liquid to be expelled from the vent valve at the top. If the inlet pressure is above 0.15 MPa, please specify separately when placing the order.

4. The SPG shielding pump system pressure is 1.6 MPa, meaning the pump's suction pressure + head height ≤ 1.6 MPa. If above 1.6 MPa, please specify at the time of ordering.

5. The electric pump has a rated frequency of 50Hz and a rated voltage of 380V, utilizing full voltage direct start. The electric pump housing has an IP54 protection rating and an F-grade insulation level.

6. The electric pump rotates in a clockwise direction when viewed from the shaft end.

7. Explosion-proof types are designed according to the specification of GB 3836.12, with explosion-proof ratings EXd II.BT3 and EXd II.BT4.
