Metering Pumps
Metering in food and beverage manufacturing is defined as controlled liquid ingredient injection. This process involves precise dosing of costly ingredients such as colors, flavors, vitamins and preservatives.
SPX offers you the widest range of metering pumps for practically every situation where liquids have to be metered and blended.
The product range includes:
- Leak-free diaphragm pumps
- Plunger pumps
A metering pump works on a similar principle as a hypodermic needle, in which a plunger draws liquid into and out of a cylinder. In a metering pump, a piston located in the pump head acts as a plunger. As the piston pulls back, it pulls liquid in; as it is pushed forward, it pushes liquid out. Volumes are varied by lengthening or shortening the throw of the piston, and speeding it up or slowing it down.
Metering configurations can be as simple as one-head/ one-pump/one piston dosing a color or vitamin or as complex as blending multiple ingredients together. For example, a mayonnaise system might have four pump heads to meter and blend vegetable oil, water, eggs and brine.
Ingredient ratios and flow rates can be automatically adjusted using a PLC touch screen. Recipes can be preprogrammed and easily adjusted to ensure product quality and maximize run times.
Common applications include: confectionery, snack food coatings, jellies, mayonnaise, salad dressings, margarine, yogurt and tomato products.
You can depend on our Bran+Luebbe metering pumps for:
- Flexibility – different dilution ratios and recipes can run on the same pump
- Accuracy – protects against out of spec product, +/- 0.5% due to precise metering gears
- Efficiency – multiple heads can be mechanically coupled together and controlled by flow meters for immediate ingredient availability
- Processing adaptability – pumps can handle a wide range of fl ow rates, up to 14,500 psi/1000 bar
- Expandability – extra pumps or automation control can easily be added to existing pumps for increased capacity, new formulations
- Control simplicity – one motor runs multiple pump heads
- Minimal hold-up time - reduces loss of costly ingredients that may become trapped in the pump head
- Ease of cleanability – CIP design options, surface roughness down to Ra 0.4
- Optimal sanitation – pumps are hermetically sealed to protect product and work environment
- Food safety – 3A, FDA, and EHEDG compliant
We stand by our products. Our service teams are available to be on site during set-up and can handle important testing and maintenance tasks if required. They can identify and eliminate any sources of errors in advance before breakdowns occur. Corrective maintenance is performed with genuine spares and consumables.
