The self-priming trash pump centrifugal ST Series is the standard for industrial and sewage applications. The heavy duty construction and easy-to-service design have made this pump the standard in the industry. The combination of different sized pumps, impeller trims and speed variations ensure that the correct capacity pump will be matched to the exact requirements of your system, whether it's a small sub-division or a large waste collection system. Self-priming trash pumps feature a large volute design that allows them to re-prime automatically in a completely open system without the need for suction or discharge check valves - and they can do it with the pump casing only partially filled with liquid and a completely dry suction line.

Working Conditions:

1. The temperature of medium no more than 80°C,the density of medium is 1.0~1.3*103Kg/m3,PH is within5~9 
2. Max diameter of solid should be less than 76.2mm 
3. Max suction lifts no more than 7.6m 
4. Volume ratio of solids in the medium ≤30% 
5. Max. working pressure and suction head pls reference performance curve and table 

Solids Handling Impeller

Two-vane, semi-open, solids handling impeller handles up to 3" (76 mm) diameter solids, depending on pump model. Pump out vanes on impeller shroud reduce foreign material buildup behind impeller and reduce pressure on seal and bearings for extended pump life.

Exclusive Abrasion-Resistant Seal

Exclusive double-floating, self-aligning oil lubricated mechanical cartridge seal with stationary and rotating face of silicon carbide is specifically designed for abrasive industrial wastewater service.

Removable Cover Plate

Removable cover plate provides quick and easy access to pump interior without disconnecting piping. Clogs can be removed and pump returned to service in minutes. Impeller, seal, wear plate and flap valve can also be accessed through cover plate opening for inspection or service.

Replaceable Wear plate

T Series pumps feature replaceable wear plates which fasten to the cover plate and can easily be removed for inspection or service. No expensive castings to replace.

Removable Rotating Assembly

Removal of rotating assembly allows easy inspection of pump shaft or bearings without disturbing pump casing or piping. On most models, simply remove four bolts from the back of the pump and the rotating assembly slides out.

Drive Variations

T Series Pumps are available as basic units for connection to customers' power source or may be flex-coupled or V-belt driven by an electric motor. Pumps may also be powered by gasoline or diesel engines. Electric motor driven pumps with "standby" engine power are also available.

Common failures of self-priming pumps

During the daily use of the self-priming pump, there will be some more common problems. For example, the self-priming pump's non-pumping problem will be caused by many different reasons, so how do we deal with these problems is the key. The reasons why the self-priming pump does not pump water include the following aspects.

Classification and difference of submersible pumps

The hot water submersible pump is used for hot spring bathing, and can also be used for extracting groundwater from deep wells, and can also be used for water lifting projects such as rivers, reservoirs, and canals. It is mainly used for farmland irrigation and human and animal water in high mountain areas. It can also be used for central air conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines, and construction site drainage. The general flow rate can reach 5~650m³/h, and the head can reach 10-550 meters.
