First 16-Foot Manholes Cast For California Customers

admin Stormwater

The new year is already looking large for Jensen Precast. Customers in Southern and Northern California are installing the first ever 16-foot concrete manholes cast at our Lockeford Branch. To the north in Mountain View, Google’s Bay View project took delivery in January of the first two 16-foot diameter precast structures, outfitted as 14,600 gpm (32-cfs) capacity packaged pump station built by Jensen Water Resources Pump Stations. To the south in Long Beach, City of Signal Hill’s Los Cerritos Channel Sub-Basin Stormwater Capture project will also install two 16-footers, which will deploy a dual Jensen Deflective Separator pretreatment system built by Jensen Water Resources Stormwater …

Water Resources: How A Submersible Pump Works

Brent Petring Pump Stations

Basic Impeller Theory The Impeller is the heart of the pump in a high flow pump station. It is the only part of the pump that adds energy to the liquid. Grossly simplifying the process, energy is added by accelerating the liquid from the smaller radius at the impeller inlet to larger radius at the impeller exit. The implications of this are that we can increase the amount of energy input into the fluid by increasing the outside diameter of the impeller or increasing the speed that it operates at. The Casing The Energy added by the spinning impeller exits as …

Pump Stations: Thrust Balancing

Bryan Bach Blog, Jensen Water Resource Blog, Pump Stations

Radial Loads When pumps operate away from their BEP, the pumps will generate uneven pressure forces inside the volute casing causing a radial thrust load on the impeller. The radial thrust load has many detrimental effects on the life of the pump. The first and most obvious is a loading on the bearings. Increased radial loads cause higher bearing reaction forces decreasing the life of the bearing. The force applied to the impeller increases as we move further and further away from the best efficiency point. Another problem caused from radial loading is the slight bending of the pump shaft, …
