STX Series – Wet prime

It is a solution for applications where the pump might run dry. It includes an auxiliary gland and oil reservoir that lubricate the seal faces and prevent dry running during priming, re-priming, or standby operation. The system features continuous circulation and cooling of the lubricant and seal faces, and allows the pump to run dry for hours without damaging the mechanical seal.

Cornell’s manure pumps come equipped with the patented Cycloseal sealing system, which leverages cyclonic action to extract solids and abrasive substances from the seal area while simultaneously purging air and gas pockets. This groundbreaking technology extends the lifespan of the seal.

Ductile iron two-blade impeller handles solids up to 3” in diameter. Impeller backvanes reduce the buildup of foreign matter and pressure in the stuffing box.

Cornell manure pumps are made with high-quality materials to ensure longevity and durability. Optional materials are also available for applications requiring resistance to abrasive or corrosive substances. CD4MCu is a duplex stainless steel that uses a two-phase metallurgical process, unlike the single-phase process typical of common stainless steels like 316. The result is a stainless steel with corrosion resistance equal to or greater than that of 316 stainless steel. CD4MCu allows the pumps to be used in more abrasive applications, offering increased corrosion resistance.

Cornell STX have a removable coverplate that provides quick access to the pump’s impeller.

Cornell STX series pumps features a heavy-duty thrust bearings with Separate Oil Reserve sized for V-belt drive loads. Separate oil filling plugs for bearings and mechanical seals with sight gauges.

Cornell Pulse is a new method to measure pump temperature and vibration in real time. The device is a small wireless unit, less than 2” in circumference, which is mounted on the pump and takes readings when prompted by the user via a mobile app. Pulse is designed to withstand tough wash-down conditions and can last up to five years with daily measurements.
