The dual head dual control pumps have two heads and two controllers for injecting two different liquids at varying ratios. This is not recommended for commercial pool use, as it is not ANSI/NSF50 approved. The dual head dual control (MDC) series remains available, as s specialty purchase.
One of the many benefits of Stenner's modular design is easy configuration to meet specific output requirements for a wide variety of applications. The 170 Series Dual Head Dual Control Adjustable Pumps are double head self-priming pumps that have fixed outputs. They have two controllers for injecting two different liquids at varying ratios. (These are for special circumstances and not recommended for pool usuage.) This Series has an output range of 0.5 to 170 GPD up to 25 psi and 0.5 to 34 GPD up to 100 psi. The Peristaltic advantage includes: automatic degassing, self-priming against pressure, and can prime up to 25 feet. All pumps are 120V or 220V and include five interchangeable tubes.
Stenner Pumps Feature:
Quick and Easy Serviceability. The practical modular design saves valuable servicing time. All major pump components are secured by stainless locking rivets, allowing the units to be disassembled quickly without tools and can easily be converted to other models.
Dependable Mechanical Control. The feed rate control in the Classic series allows the pump's output to be scaled from 5% to 10% with the simple turn of the external dial ring.
Less Down Time. The peristaltic pumping action eliminates down time from prime loss due to off-gassing solutions and eliminates the need for troublesome degassing valves.
Easy Tube Maintenance. Simple periodic tube replacement minimizes down time and maintenance costs. All that is required is setting the tube in place and guiding it as it threads itself into position. No lubrication is required.
Safe and Versatile. Various solutions and chemicals can be metered without harm to the unit because they are pumped without exposure to air or the moving mechanical parts. Hydraulic fluids are not used and therefore can not leak into the solutions metered.
Interchangeable Components. The snap-fit modular design allows easy conversion to another model providing customers with flexibility for various applications.
Stenner's quality peristaltic pumps are recommended for use by the leading manufacturers of chemical controllers. Their product return rate is less than 1/4 of 1%. Accessories include: Suction Tubing, Strainer, and Ceramic Weight; Discharge Tubing and Injector; Peristaltic Feed Tube and Mounting Bracket.
One-Year Limited Warranty.
