What's the difference between a septic grinder pump, sewage grinder pump & sewage effluent pump?
The general name for these pumps is sewage grinder pumps if they are intended to grind and move black water or sewage. A sewage grinder pump is synonymous with a septic grinder pump.
If the pump is intended only to move clarified effluent, say from a septic tank to a drain field the proper term to use is sewage effluent pumps.

What Type of Septic Pump or Sewage Pump Should I Buy?
The type of sewage pump you need depends on how it will be used. The pumps at left may have been a misapplication for this municipal lift station ,which may explain why we found these discarded units on the site. Septic pump systems vary by these parameters:
Septic pump manufacturers provide a pump selection and sizing table that is used to guide the installer in selecting the proper pump. We've seen sewage handling systems where the wrong type or wrong capacity of pump was installed, sometimes as an attempt to "save money."
Two types of sewage pumps are used in residential applications, sewage grinder pumps or sewage ejectors pumps, and non-clogging sewage ejector pumps. We describe these next at Septic Pump Duplex System Designs

Frequently Asked Questions (FAQs)
Inline Sewage Grinder Pumps
I purchased a modular home 14 years ago, it's 66 ft long and I don't feel that the drop angle of the drainage pipes from the home to the septic is right. Is there a inline ejector pump available? - B.K. - 3 Aug 2013
A competent onsite inspection by an expert usually finds additional clues that would permit a more accurate, complete, and authoritative answer than we can give by email alone. You will find additional depth and detail in articles at our website. That said I offer these comments:
I'm not sure I correctly understand what you are asking about with the term "inline ejector pump" but I am guessing you want to know if there is a sewage pump that is placed horizontally in line along the route of a drain system.
A problem faced by simple residential sewage grinder pumps is that we need a way to know how to turn the pump on and off when needed - manufacturers solve this problem with a modest plastic reservoir chamber; sewage or wastewater flows into the reservoir; when the wastewater level reaches a level high enough to justify a pump-on cycle, a float switch turns on the pump which grinds and pushes sewage to an outlet plumbing line.
Indeed there are types of "in line" sewage grinder pumps available from severasl manufacturers listed in our article SEWAGE PUMP BUYERS GUIDE including Crane. A quick search of inline grinder pump products returns first high capacity municipal sewer system pumps that are not intended for residential use. For example, and quoting from Crane, include pumps handling flows up to 1,200 gpm and fitting pipe diameters with a 1-4" discharge. Inline pumps are available in both vertical and horizontal pipe hookup models, and some industrial models are indeed intended for sewage pumping such as

Some smaller inline sewage pumps as well as larger municipal equipment include
Watch out: not all of these are intended for sewage pumping:
I offer these suggestions to address your concern for possibly inadequately -sloped building drain piping that is resulting in clogs and backups:
1. before buying and installing a grinder pump, inline or reservoir type, it makes sense to get an accurate diagnosis of the actual problem. Indeed my cousin's bragging about the great deal he got on the price of a house in Phoeniz was mitigated by the discovery that when he flushed toilets sewage came up through the first floor bathtub drain. An investigation by a savvy plumber included some elevation measurements easily made by checking the depth and elevation of the drain line at various cleanouts. He found that the builder had installed a long nearly-flat building drain line between the house and the sewer line. The fix was not easy nor cheap and would have involved excavating to re-set the line.
But more often recurrent sewer line clogs and backups are due to a more localized problem such as a partly broken, cracked, root-clogged, or otherwise impeded section of a drain line. If a plumbing drain camera inspection of your drain system discovered that this is the problem at your building it might make more sense to open and fix the bad drain section than to try to keep forcing sewage past a recurrent clog point that may in time become a solid clog - a section of piping that ultimately has to be opened and replaced or reparied, wasting the prior cost of the grinder pump.
2. At SEWAGE PUMP BUYERS GUIDE we list a number of companies offering a large variety of sewage pumps - give some of these folks a call to see what products they recommend.
