Industrial-strength pumps manufacturer and distributor Verder now offers a new, FDA-approved high-pressure, double-acting diaphragm pump, suitable for filter-press applications in the brewery and winery industries and applications where the discharge pressure is higher than the available compressed air pressure.
The new VA25-HD (DA) high-pressure diaphragm pump features the traditional advantages associated with high-pressure pumps, including stalling against closed discharge, which means that no safety pressure valve is required; boosting pressure double the compressed air pressure; and not needing ancillary equipment to regulate flow at raising discharge pressures.
Some features that are unique to this pump include the fact that is has the same maximal flow rate as a standard Verderair VA25 diaphragm pump; it is also double acting, and therefore produces stable and efficient flow; and it has a high-pressure switch that allows for it to be more efficient.
It is, therefore, the ideal pump for filter-press applications, used in the brewery and winery industries.
The existing range of high-pressure diaphragm pumps, which are single-acting pumps, can deliver fluid pressures of up to double the supplied compressed air pressure. This results in a pulsating flow, high compressed air consumption and a 50% reduction of the flow rate.
In addition, the VA25-HP (DA) pump has a switch to change the pump operation from low pressure to high pressure. At the low-pressure setting the pump operates in normal, low-pressure mode with optimum use of the compressed air. When operating in high-pressure mode, the pump boosts the liquid pressure to double the compressed air pressure, with flow rates double that of a single-acting, high-pressure pump.
