Certain waste items like diapers or articles of clothing or towels will clog regular pumps. Even if the pump can pass along some of these things, if the solid is larger than the pipe diameter, then the items can clog the pipes. Grinder pumps are designed to grind waste into a fine slurry. But many grinder pumps can also be susceptible to problems.

Grinder pump trouble! Yes, a grinder pump can fail. For one, it's electrically powered, and in the case of a power outage, it will stop working. The motors in the grinder pump may also burn out. Early warning signs that this has happened include multiple clogged drains and toilets in the house and foul odors coming from drains.

Pumps are becoming more efficient and capable of handling the challenges of modern sewer systems, and pump manufacturers are developing Web-based tools to support pump selection. Distributor application engineers can log into a portal and enter the static head and length and size of the pipe, and within minutes, pick the pump that is most efficient for …

Grinders are used to simply shred the materials small enough, so that the pumps can do their job efficiently. What has changed with how grinders are used in sewage sludge systems? While protecting pumps still remains the top application's, the sophistication of biosolids processing in treatment plants has evolved significantly over the last 45 years.

Systemwide Efficiency Considerations for Wastewater Pumps. Quality motors can create high wire-to-water efficiency and result in energy savings. Mechanical efficiency has been a topic of conversation since energy conservation became a priority. This began in the 1970s and '80s with the establishment of the Department of Energy (DOE), which ...

The choice between GP and STEP systems depends on three main factors, as described below: Cost: On-lot facilities, including pumps and tanks, will account for more than 75 percent of total costs, and may run as high as 90 percent. Thus, there is a strong

Pump considerations. . 1. If the pump has any small faults, remember not to let it work. If the filler of the pump shaft is worn out, it should be added in time. If the pump is used continuously, it will leak. The direct effect of this is that the motor consumes more energy and can damage the impeller. 2.

Quick rule of thumb- Only use grinder pumps when flow rate is less than ~100 GPM. The grinder pump allows you to use a 1-1/2" or 2" discharge pipe because solids are reduced in size and can be transported at velocities> 2'/sec. For higher flowrates, use 4" dia. pipe as long as you have transport velocity >2'/sec.

A grinder pump also known as a sump pump, is a waste management tool that is made to be utilized in dishwashers, toilets, showers and washing machines among other appliances, which give off waste water. With the grinder pump you can have your solid waste which is in the water being turned slurry, then transported to the sewer lines.

**All pumps off elevation (Suggestion: Use the average elevation between the "lead pump on" and "all pumps off". This will give the mid point of the pump operation range.) 2) Friction head will vary during pumpdown of the wet well, as noted above.
