Deflector panels and drop bowls are both used to reduce the amount of turbulence in the wet well. Turbulence can have several adverse affects on the lift station. First, unimpeded water, cascading down onto the pumps, can damage them over time. This is especially true with pump cables, which are normally mounted on the top of the pump. If the water breaks or interrupts the connections, power can be cut from the pumps. Cascading water …
When should a deflector panel be used instead of a drop bowl?
Romtec Utilities determines between a deflector panel and a drop bowl by looking at the inflow rate to the wet well. In most situations, inflow rates below 200 gpm can be handled by a drop bowl. When inflow rates are higher than 200 gpm, the drop bowl size required to catch the inflow encroaches on other elements in the wet well. Pulling out the pumps for maintenance is one such activity that limits the space …
When do I know if I need explosion proof pumps?
Typically the type of water and the classification of the space are the main factors in deciding when to use explosion proof pumps. In the majority of wastewater applications, explosion proof pumps are preferred so that gases coming off the water cannot trigger an explosion. Industrial water applications can also require explosion proof pumps, such as with oily water, chemical water, cleaning water, and more. With clean water and most stormwater scenarios, explosion proof pumps …
What type of fall protection if provided for a manhole when the hatch is open?
Romtec Utilities typically designs lift stations with a bright orange safety grate built into the hatch. The two piece safety grate lies underneath the hatch doors as a secondary fall protection for the well. Lifting the safety grate is assisted with compression springs to alleviate most of the weight.
What pump brands or manufacturers do you offer?
Romtec Utilities is not affiliated with any single pump manufacturer. Romtec Utilities offers all major pump brands on our complete, site specific lift stations. If you have a specific preference or standard, Romtec Utilities will be sure to use that pump manufacturer in our design and engineering services.
