Little Giant Sewage Pumps
Little Giant Sewage Pumps (Sewer Pumps) are mainly designed to discharge both solid and liquid waste from sewage basins, receptacles and tanks. They are typically installed in the lowest area of the location where waste water and solids removal is needed, such as basements.
All Little Giant Sewage Pumps are fully submersible and are generally divided into automatic models (with float switch) and manually operated models.
Sewage pumps are sized based on the system requirements and pre-existing conditions, such as size of solids, system pressure drop, size and length of discharge pipes, elevation, etc.
Little Giant 9S-CIM sewage pumps:
9S-CIM series (such as 509400 model) features manually operated and fully submersible sewage pumps. They have 2" discharge outlet (3" optionally), can handle large solids of up to 2" in diameter, have 4/10 horse power rating and are best suited for medium to low pressure drop applications.
Little Giant 9S-CIA sewage pumps:
9S-CIA series Little Giant sewage pumps (i.e. sku# 509500) are automatic and come with a float switch to shut off the pump when the water level reaches a certain point. Similar to 9S-CIM series, they can handle large solids of up to 2" in diameter, have 2" or 3" discharge size and are best suited for medium to low pressure drops.
Little Giant 10S-CIM sewage pumps:
10S-CIM series Little Giant sewage pumps, such as sku#'s 511400 and 511420 are designed for applications with higher pressure drops and higher flow requirements. 10S-CIM models are manually operated sewage pumps.
Little Giant 10S-CIA sewage pumps:
Fully automatic, the 10S-CIA series Little Giant sewage pumps come with a float switch, which activates/deactivates the sewage pump once a certain waste water level is reached. These are designed to handle 2" size solids and are well suited for applications with high pressure drops and high flow requirements.
Little Giant 10SH-CIM sewage pump:
This model is specifically designed for use in high head applications and has a head rating (shutoff pressure) which is 40% greater than the regular 10S models. This model is manually operated and can handle 2" size solids.
