H25 Hydra-Cell pumps are designed to output a flow range of 2 to 20 GPM at pressures from 50 to 1000 PSI. Available with both alloy and non-alloy pump ends, H25 Hydra Cell pumps are used across a multitude of industries. In paper mills H25 Hydra Cell pumps are used for trim squirt applications, in power generation facilities they are used for reagent injection and some of the worlds largest breweries use H25 Hydra Cell pumps for blasting beer kegs clean prior to refilling them.
Although capable of higher pressures and thus a natural for spray drying food ingredients or etching printed circuit boards with ferric chloirde, often H25 Hydra Cell pump applications involve much lower pressures simply due to their sealless design.
Other positive displacement pump designs have cups, packing or mechanical seals separating the rotary components from the fluid end components and these eventually wear and need to be replaced. Perhaps even worse for some applications are the consequential pump damage as a result of seal failure or the fugitive emissions into the surrounding environment. H25 Hydra Cell pumps are sealless and thus outshine other types of pumps when fluids contain abrasives, are hazardous or are at an extreme temperature. The reason for this is that H25 Hydra Cell pumps have no sliding or rotating parts exposed to the pumped fluid; they are not dependent upon the fluid being pumped for lubrication or cooling. H25 Hydra Cell pumps are undamaged operated dry or with a reduced/closed inlet condition. About the only way you can damage an H25 Hydra Cell pump is by operating it beyond its maximum pressure rating or pumping a fluid incompatible with the materials used in the pump head. The H25 Hydra Cell pump sealless design significantly enhances reliability and reduces costs from both reduced downtime and spare parts cost perspectives.
The extreme volumetric efficiency of H25 Hydra cell pumps enable them to satisfy API 675 metering pump performance standards with regards to linearity, steady-state accuracy and repeatability. Its pumping motion is gentle, so H25 Hydra Cell pumps are used for transferring shear sensitive fluids such as liquid latex. Capable of handling viscosities of over 5000 SSU, H25 Hydra Cell pumps are also used for metering wax and resin in the manufacture of chipboard.
We can provide the bare shaft pump or a complete pump and motor skid (belt or direct driven). All of the pumps and almost all the components are manufactured here in the USA!
There are three types of repair kits for H25 Hydra Cell pumps: valve kits, diaphragm kits and "complete fluid end kits", with the latter being a combination of both a diaphragm and valve kit.
The expected wear life for the check valve assemblies within H25 Hydra Cell pumps is over 1 year of continuous operation, so 8760+ hours and that would be based on a fluid containing few particulates, such as "industrial water". Slurries and other fluids which are either corrosive or abrasive might require check valve replacements as frequently as every 4000 to 6000 hours of service. Check valve wear can be reduced by choosing materials that are more resistant to erosion and corrosion. Following is an example of the material options for the fluid end components of an H25 Hydra Cell Pump.
The diaphragms and o-rings are not considered to have a "wear life"; they have been tested for over 20,000 hours of continual use without any indication of wear. They can be damaged when the pump is over pressurized and if the fluid is incompatible with the available elastomers. The PTFE diaphragms are the one exception to the "unlimited" wear life for diaphragms because its design consists of a stiff layer of PTFE bonded to an FKM substrate and thus PTFE diaphragms should probably be replaced annually.
You can forecast spares cost and compare it to your existing pumps by inputting a pump part number into our Hydra-Cell pump repair kit pricing tool. Use the H25 catalog pages to generate a part number (last page of the PDF file below) and then input that part number into the kit part numbering program and you 'll see each each kit and its cost.
Our Hydra Cell pump inquiry form is designed to gather all the information necessary to provide a proposal; we usually respond within a few hours but you can also call us to speak with a sales engineer imediately.
