AgXcel FAQ!
GX5 Diaphgram versus GX5 Centrifugal pumps?
Priming:
- Diaphragm pumps are self priming pumps, which means that if the pump is mounted far away from the tank and if the pump sits higher than the bottom of the tank, the diaphragm pump is still able to pull product to prime itself.
- Centrifugal pumps are not self priming and must be mounted below the level of the tank and should be mounted close to the tank.
Flow Output:
- The diaphragm pumps do not have as large of a flow range as a centrifugal pump does. The smallest diaphragm pump has a flow range of 0.5 – 18 GPM and the largest model from 5 – 55 GPM. The centrifugal can apply over 100 GPM in the right conditions.
Positive Displacement:
- AgXcel diaphragm pumps are positive displacement pumps, meaning that for every revolution the diaphragm pump makes, the same amount of liquid is applied for each revolution. These style of pumps are preferred for infurrow applications, as well as for 2×2 applications as well.
- Centrifugal pumps are not positive displacement.
PSI Rating:
- AgXcel diaphragm pumps are rated at 220-290 PSI (model dependent). Now the rest of the banjo plumbing fittings and hoses are not rated that high, but since the pump has this high of a rating, this means that you will not have flow loss at higher pressure ranges when using the GX5 pump.
- The AgXcel centrifugal pump is rated for up to 120 PSI. But depending on your flow rate, you may not be able to achieve this this high of a pressure rating. Meaning if you increase your flow rate, you may not be able to achieve as high of a pressure rating.
Material:
- The AgXcel GX5 diaphragm pumps are made of 316 stainless steel with viton seals and BlueFlex diaphragms
- The AgXcel GX5 centrifugal pump is a black epoxy coated cast iron pump with FKM seals
