A diaphragm structured for use in a diaphragm pump useful to pump a working fluid includes a first non-planar layer and a second non-planar layer. The second non-planar layer is independent from the first non-planar layer, but engaged to the first non-planar layer so that the first non-planar layer and the second non-planar layer form a closed space therebetween and travel together while flexing in an intake direction or a discharge direction within a pumping assembly of a diaphragm pump.

A positive displacement pump includes a housing surrounding a drive chamber and a diaphragm compartment. A drive element is inside the drive chamber. A diaphragm is inside the diaphragm compartment and divides the diaphragm compartment into a fluid chamber and a cavity. A shaft connects the drive element and the diaphragm. A breather valve is fluidically connected to the cavity and is configured to allow air to exit the cavity. The cavity is fluidically disconnected from the drive chamber.

A system or method for monitoring drilling fluid. The system may comprise a fluid supply, wherein the fluid supply houses a drilling fluid, a pump, wherein the pump is fluidly connected to the fluid supply, a dispensation unit, wherein the dispensation unit is fluidly connected to the pump, and a process vessel, wherein the process vessel is fluidly coupled to the dispensation unit. The dispensation unit may comprise a housing, wherein the housing may comprise an internal cavity, an inlet, and an outlet. The dispensation unit may further comprise a top plate, wherein the top plate is configured to form a seal over the housing, and a diaphragm, wherein the diaphragm is disposed between the top plate and the housing. A method may comprise pumping the drilling fluid through a dispensation unit, actuating the dispensation unit, and determining a property of the drilling fluid.

A cassette integrated system.
