Overview:
The GSSN series drain pumps are designed by integrating advanced technologies both domestically and internationally. They are specifically tailored for use in power plants (thermal power plants), particularly in areas such as thermal network heaters, low-pressure heaters, and air heaters. These pumps can also be applied to convey other media with physicochemical properties similar to water in various engineering applications. They feature high efficiency, energy savings, economic reliability, a high degree of standardization, and an extended service life. With their remarkable flexibility, these pumps can meet the operational requirements of different unit operating modes and adapt effectively to varying load conditions of the generating units.
The product has the following advantages:
1. It adopts a highly efficient and energy-saving hydraulic model with high efficiency and excellent cavitation resistance.
2. Low vibration and noise, reliable operation, and easy maintenance.
3. The pump’s bearing and sealing components have been improved, extending their service life.
4. The components have a high degree of standardization and are fully interchangeable.
Performance range:
Flow rate Q = 3–300 m³/h
Head H = 80–300 m
Temperature T = room temperature ~ +450℃
Model meaning:
GSSN100-210
GSSN—Two-stage, Single-suction Sewage Pump
100—The rated flow is 100 m³/h;
210—Rated head is 210 m
Structural features:
The GSSN series of slurry pumps are available in two structural types: a two-stage, single-suction, double-bearing type and a two-stage, single-suction, cantilever type, as shown in the structural diagrams. The pump casing features a radial split design, and its mounting method is horizontal centerline support, which minimizes deformation and displacement caused by thermal expansion and contraction. Pump bodies with discharge diameters ≥100 mm are designed with dual-volute chambers to balance the radial forces acting on the pump.
The shaft end seal can be either a packing seal or a mechanical seal.
The sealed cavity is designed according to industry standards: optimizing cavity dimensions to enhance operational efficiency.
The sealed cavity can be equipped with various cartridge-type, balanced, and bellows mechanical seals according to engineering requirements.
Depending on the operating conditions, the sealing cavity can be equipped with an optional water-cooled jacket.
The impeller features a single-suction design and is entirely cast as a single piece. It is connected to the shaft via a keyway and undergoes dynamic balancing together with the rotor. Both the casing sealing ring and the impeller sealing ring are standard, replaceable components; their excellent fit is ensured by differences in material and hardness. The symmetrically arranged inlet ports of the two impellers help balance axial forces, while any residual axial force is borne by thrust ball bearings.
When the pump features a cantilever support structure, the bearing housing is available in either cast iron or cast steel and includes a large oil reservoir for bearing lubrication. At the coupling end, two thrust ball bearings are mounted back-to-back, while at the opposite end, a single radial ball bearing is installed.
When the pump adopts a two-end support structure, both ends of the pump are equipped with bearing housings of identical size. These housings are made of either cast iron or cast steel and are bolted onto the bracket (bearing frame). They are positioned using mating locating shoulders. At the coupling end, a set of radial ball bearings is installed; at the opposite end, two sets of thrust ball bearings are mounted back-to-back.
All bearings are lubricated by oil slinger rings; for special requirements, oil mist lubrication can also be selected. The bearing housing is cast with cooling fins on its exterior, enabling air cooling (T < 120℃) and water cooling (T ≥ 120℃). The bearing housing is equipped with both a plastic circular oil level indicator and an oil cup for monitoring and controlling the oil level. At both ends of the bearing housing, copper dust shields extend into the inner bore of the bearing cover, effectively preventing the ingress of dust or moisture while also sealing against oil leakage. In the unlikely event that the bearing should fail, these dust shields can still provide structural support.
To enable inspection of the impeller, bearings, and shaft seals without dismantling the suction and discharge piping system during maintenance, this series of pumps features a flexible diaphragm-type extended coupling that is extremely easy to assemble and disassemble.
