Grinder pumps are typically used for light weight sewage applications, whereas chopper pumps are used for tough solids handling applications. The chopping system consists of a set of rotating cutters that are keyed to the shaft and work in conjunction with the stationary cutters, which are bolted to the suction plate.
Grinder pumps can be installed in the basement or in the yard. If installed in the yard, the holding tank must be buried deep enough that the pump and sewage pipes are below the frost line. A grinder pump is different from a sump pump or effluent pump. There are two types of grinder pumps, semi-positive displacement (SPD) and centrifugal.
When the sewage level rises to a predetermined point, a pump will be started to lift the sewage upward through a pressurized pipe system called a sewer force main if the sewage is transported some significant distance. The pumping station may be called a lift station if the pump merely discharges into a nearby gravity manhole. [4]
Linde Hydraulics was established as a division of Linde Material Handling, a Linde AG business unit. Production of the first forklift truck with hydrostatic transmission began. 1984: Linde and Linde Hydraulics introduced the load sensing valve technology. 1994: Introduction of the 02 Series axial piston pumps and motors with a swash angle of 21 ...
The pump swivel angle covers both positive and negative flow direction. Disadvantages: The pump cannot be utilized for any other hydraulic function in an easy way and cooling can be a problem due to limited exchange of oil flow. High power closed loop systems generally must have a 'flush-valve' assembled in the circuit in order to exchange much ...
Crown later decided to stop making so many one-of-a-kind trucks and developed two lines of E-Z Lift Trucks: an H series (hand-operated) and a B series (battery-operated). In 1959, when its lift trucks had annual sales of about $50,000, antenna rotators had annual sales of $700,000, [9] but the transition to the lift truck business was under way ...
The capitalized cost of operation and maintenance of lift stations and emergency power supplies usually justifies considerable first cost for excavation or tunneling to build a gravity sewer. [3] Sewage treatment is most efficient at centralized locations; and pumping is often required to lift sewage from lower elevations to the sewage ...
Vacuum truck. A vacuum truck, vacuum tanker, vactor truck, vactor, vac-con truck, vac-con is a tank truck that has a pump and a tank. The pump is designed to pneumatically suck liquids, sludges, slurries, or the like from a location (often underground) into the tank of the truck. The objective is to enable transport of the liquid material via ...
