Availability: Out of stock

We’re committed to providing you with the finest pump your money can buy. That’s why we’re constantly evaluating and reassessing our product – continuing to improve it. And we’re confident you’ll find SSP’s linear pump to be the best on the market as well. Here’s why:

    Resettable safety switchPerhaps the most important difference of all. SSP’s advanced design employs a resettable safety switch rather than a breakable safety screw, which you know, if you’ve ever tried to replace one, is a difficult and time-consuming task.

    Greater flow rates than the competitionThe greater the flow rate, the greater the amount of aeration delivered to the aerobic treatment system. Published flow curves show Septic Sewage Pumps linear compressors deliver 10 to 20% greater flow than the competition.

    Higher pressure values than the competitionHigher pressure allows the pump to overcome back pressure in your aerobic treatment system caused by clogged diffusers and high water depth. Published flow curves show our compressors deliver higher maximum pressure than the competition

    Push to connect wiringThe SSP unit features removable wiring connectors making the pump much easier to service. Other brands use soldered connections which make them susceptible to cracking or breaking.

 UL/NSF Certification All Septic Sewage Pumps linear compressors are UL/NSF certified. You know that means quality and performance you can trust! Not all manufacturers are.

 Outstanding Service We know it’s not only important to sell a high-quality product, but to also stand behind it with excellent service and support comparable to none. We have a strong commitment to that philosophy, with more team members here in the USA dedicated to servicing your aeration needs than any other linear compressor manufacturer.

2 Year Warranty. (1 Year Longer Than Hiblow)
