Diaphram Pumps

Diaphram Pumps deliver dependendable performance and low maintenance. Ideal for slow seepage applications where a centrifugal pump would ordinarily lose its prime. Diaphram pumps are perfect for muddy water, sludge or any water with a high percentage of solids. Diaphram pumps use a positive displacement design rather than centrifugal force to move water throught the casing. This means that the pump will deliver a specifiic amount of flow per stroke revolution or cycle. The Diaphram pump provides the lowest rate of discharge and head by comparison of any contractor pump.

Dewatering pumps are commonly expected to suck water out of a trench, unfortunatley that would be an incorrect expectation. Water will always take the path of least resistance; the dewatering pump provides the water with that path. Although there are two main designs of dewatering pumps, they both serve the same purpose; to move water from one point to another.

The first design of dewatering pumps is the centrifugal design. This type uses a rotating impeller to draw water into the pump and pressurize the discharge flow. Common types of centrifugal pumps are the trash, standard and submersible pumps. The trash pump was given its name because of its ability to handle large amounts of debris. Generally the trash pump can handle spherical solids up to 1/2 the diameter of the suction inlet. The standard centrifugal pump is a good choice of common dewatering situations. The standard centrifugal pump is best used in clear water applications with limited solid handling capability. Typically the standard centrifugal pump can only handle spherical solids 1/3 the diameter of the suction inlet. The last type of centrifugal dewatering pump is the submersible pump, their compact design make them ideal for wells and jobs with limited space. True to its name, the submersible pump can be placed right into the water that it is pumping. The pump motors use a vertical shaft to turn the impeller and generate the velocity needed to create the discharge pressure.

Water flows in through the bottom and is discharged out the top of the pump casing.

The second design of dewatering pumps is the positive displacement design. These pumps deliver a fixed amount of flow per cycle through the mechanical contraction and expansion of a flexible diaphragm. The common positive displacement pump is the diaphragm. The diaphragm pump uses drive shaft to turn an offset connecting rod that is coupled to a flexible diaphragm. The connecting rod alternately rises (expands) and lowers (contracts) the diaphragm at a rate of 60 RPM. The diaphragm pump has the ability to handle air without losing its prime and it can also handle solids greater then 25% by volume. Because the diaphragm pump has no impeller or volute they do not run the risk of being damaged if they are run dry for a long period of time.
