Why Specify Scaletron™ Volumetric Feeders?
10 Reasons to Choose Scaletron’s Volumetric Feeder
Scaletron’s Model VMF-28™ Volumetric Feeder offers many advantages that our competitors can’t match. Here are ten reasons that we think make it a great product.
#1 - Industries & Applications – Water, Wastewater, Industrial & More
The VMF-28 is ideal for use in municipal water systems for drinking water treatment. Systems that draw surface water from reservoirs and rivers use powdered activated carbon to control algae blooms, oil and other industrial wastes in the water supply. Many systems are old, inaccurate and due to the dust, operators hate them. In addition, PCB’s, THM’s, TCE’s and VOC’s are on everyone's mind because of tightening government regulations. Activated carbon is also the best and most economical way of treating for these problems.
In addition, there are numerous applications such as wastewater treatment and industrial process water treatment where dry powders are used to filter out chemicals and petroleum products. For these applications we offer systems designed for aluminum sulfide (a flocculant), lime and soda ash as well as systems for feeding polymers. If come across applications for any of these materials, please contact us for more information.
#2 - Integrated “Loss in Weight” Batching System - We Have the Best Solution
The VMF feeders are available with a gravimetric feeding option that measures dosing amounts via "loss in weight". Besides saving operators time, this option improves accuracy because the integrated scale continually monitors weight loss or gain. Heat, moisture and other environmental variables can cause additives like lime and carbon to absorb or dissipate water. When the material absorbs moisture, its density increases and it is subject to clumping making dispensing by screw feed alone subject to wide swings in the amount of carbon injected into the water system. This can result in not enough, or too much material being introduced into the treatment process. The Scaletron feeders eliminate this risk by providing operators with constant real time assessment of the total mass of additive being used. Precise dosage amounts are automatically weighed and added to treatment processes without requiring an operator to measure and weigh amounts.
In addition, Scaletron’s VMF-28 utilizes four load cells versus some competitors who use just one. With dry powders loads can frequently become off-center resulting in inaccurate readings if you only have one load cell on the scale. In addition, the load cells are positioned so that they just weigh the hopper. All competitive models weigh the entire frame making the product being weighed much less that the capacity of the load cells and harder to provide accurate readings.
#3 - Rugged Construction – We Offer a Two Year Warranty
The VMF-28 features a rugged, steel frame protected by corrosion resistant finish. The hopper, augers, loading boxes and piping are all stainless steel.
#4 - Heavy Duty Motor & Drive Mechanism – for Reliable Operation
The VMF-28 employs a direct drive, variable speed, TENV 90 VDC washdown gear motor with quick change feed screws. To meet a range of application requirements, standard motors are available from 1/8 HP to 1/4 HP while optional explosion proof and Washguard motors are available from 1/3 HP to 1 HP.
#5 - Multiple Control Options – for Accurate Feed Rates
Scaletron offers a number of control options to insure accurate feed rates. Utilizing the optional SCADA programmable or HMI PLC touch screen controllers, the VMF-28 can be programmed to automatically adjust the feed rates of the material being added.
#6 - A Range of Loading Configurations – to Fit Any Application
Scaletron offers a range of efficient, time-saving material loading options including:
- 50 lb. Bag loaders - to reduce dust
- 50 lb. Glove box bag loaders – fully sealed to eliminate dust
- FIBC bulk bag (super sack) unloaders – hoist or fork lift style
- Direct feed from silos - for large scale operations
#7 - Wetting Cones & Mixing Tanks – to Create Any Solution
Scaletron offers mixing tanks from 35 to 100 gallons and wetting cones to produce solutions or slurries by mixing of dry chemicals with water. For example, we offer a pre-packaged system including mixing tank and all required options for fluoride dosing.
#8 – Wide Range of Accessories – to Accommodate Diverse Materials
Accessories for the VMF are designed to enable efficient and accurate processing of materials from powders to pellets and include:
- Multiple auger sizes and styles
- Multiple discharge spout styles
- Vibratory agitators
- Particle crushers
- Dust collectors
- Lift-off, hinged or fixed lids for hopper
- Hopper extensions for additional capacity
- Base stands and elevated loading platforms
#9 - Quick Installation - with Fully Configured Systems
Installation is a breeze as VMF systems are shipped fully configured for each specific application and ready to use. We stand by ready to assist our local distributor and you through the entire process.
