Stenner 45MPH2: MSRP: $400.00 pump only!
Wide Range of Features and Flexibility
One of the many benefits of Stenner's modular design is easy configuration to meet specific output requirements for a wide variety of applications.
Completely self-priming, can operate dry
* Six interchangeable tube sizes for control of feeder output
* Precision pumping of fluids up to 170 gallons per day (514.8 liters @ 50 Hz)
* Will not clog from dirt and minor debris
* Can pump against pressure of up to 100 PSI (maximum GPD 40) up to 6.9 bar (maximum LPD 121.1)
* Check valves not required under 25 PSI (1.72 bar)
* Reproducible within 2% of outputs
* Tube lubrication is not required
* Vertical or horizontal mount
* Spill recovery feature included
* Advantages That Save You Time and Expense
Quick and Easy Serviceability
Stenner?s practical modular design saves valuable servicing time. All major feeder components are secured by stainless steel locking rivets, allowing the units to be disassembled quickly without tools. This also makes adding capacity a snap.
The peristaltic pumping action of Stenner feeders eliminates down time from loss of prime caused by gaseous solutions or troublesome degassing valves. Rather than relying on diaphragms or foot valves, Stenner feeders create a peristaltic flow with rotating rollers that compress and dilate the pumping tube. Hydrogen peroxide can be pumped without concern about vapor lock.
Simple periodic tube replacement minimizes down time and maintenance costs. All that?s required is setting the tube in place and allowing it to thread itself into position.
Dependable Mechanical Control
Stenner?s patented control mechanism allows the pump?s output to be scaled from 5% to 100% with the simple turn of a dial.
Stenner manufactured the first high-pressure peristaltic metering pump that could operate reliably and consistently against pressure of up to 100 PSI.
Chemicals such as undiluted muriatic acid and chlorine can be pumped without harm to the system because they are metered without exposure to air or to moving mechanical parts. Since no hydraulic fluids are used, there is no possible leakage to the chemicals being metered.
