**Product Name: BB1 Double Suction Pump, Centrifugal Pump**
**Performance Range:**
- **Flow:** Q = 144–12,500 m³/h
- **Head:** H = 9–140 m
**Structure:**
The SH pump features a horizontal open casing with a double suction impeller. The suction and discharge pipes, along with the lower part of the pump body, are cast together, eliminating the need to remove pipelines or the motor when inspecting the pump rotor. This design ensures easy maintenance and efficient operation.
**Model Specification:**
- **10 SH – 13 A**
- **10**: Suction diameter (inches)
- **SH**: Single-stage double suction horizontal pump
- **13**: Integer divisible by 10
- **A**: Impeller cut once; the order is A, B, etc.
**Shaft Sealing:**
The pump uses soft packing for sealing, allowing the sleeve to be replaced easily. It can also be equipped with a mechanical seal based on customer requirements.
**Transmission:**
The pump is driven via a flexible coupling connected to the motor. From the drive end, the pump rotates counterclockwise (clockwise rotation can be provided upon special request).
**Bearing and Balance Device:**
Rolling bearings or sliding bearings are installed at both ends of the pump shaft. Axial force is balanced by the double suction impeller, with residual axial force managed by the rolling bearing. Rolling bearings use grease lubrication, while sliding bearings use thin oil lubrication.
**Materials:**
- **Casing:** Cast iron
- **Shaft Sleeve:** Cast iron
- **Sealing Ring:** Cast iron
- **Shaft:** High-quality carbon steel
- **Impeller:** Cast iron or cast steel
Depending on the medium being pumped, materials and models may vary.
1. For clean liquids without solid particles, SH type pumps are made of cast iron, while SHG type pumps use cast steel, carbon steel, or stainless steel. Rotor parts are carbon steel or stainless steel.
2. For seawater or other corrosive media, SHN type pumps use nickel cast iron, and SHF type pumps use stainless steel.
**Motor Base:**
When the motor power is below 110 kW, a standard base is used. If the power exceeds 100 kW, special instructions must be provided. Any specific motor requirements should be mentioned in the order.
