Essentially the valve less pump is a reciprocating plunger pump. However a reciprocation pump requires two non return valves one each at the suction and the discharge port of the pump for it normal functioning. Such non return valves causes’ severe problem in certain application. To overcome this problems the valve less pump provides the solution without the use of discrete non return valves, this is explained below. Our BALYOG provides this valve less function. The mechanism enables combine rotary and reciprocating motion to the plunger in synchronism, thus giving it characteristics of variable delivery positive displacement pump. The BALYOG mechanism consists of a yoke and ballpin. The yoke and the ballpin axis lie on a plane but their axis are tilted. During the circular motion of this mechanism due the the inclination of the ballpin axis with respect to the yoke. The ballpin wobbles with respect to the yoke imparting synchronized helical motion to the plunger. The plunger has specialy design slots with respect to the suction and discharge ports. These enable valve less function. The discharge of the pump can be varied by varying the angle between the yoke and the ballpin. A fine screw enables precise control and large graduated dial gives high resolution. The valveless pump is advantageous in application where non return valves can get chocked, where the operation of the valve becomes sluggish due to the nature of the fluids handled. However there is little limitation in respect to the volumetric efficiency, this limitation is due to the internal clearances required for running of the plunger. The clearances cause some internal leakages at higher pressures Vacuum pumps DENCIL VACUUM PUMPS is a leading manufacturer, exporter and Servicing of all type of Vacuum Pumps ranging from 100 L.P.M to 10000 L.P.M , Compressors and Complete Vacuum System as per customers requirement with technical know how from our Design & Development Team.

Flow improvers, also known as drag reducing agents (DRA), are injected into pipeline fluids to reduce turbulence. The associated reduction in frictional pressure drop can provide significant benefits to pipeline operators by providing additional pipeline throughout, the ability to operate in reduced pressure-drop conditions, or a combination of these effects. Due to its heavy molecular weight and high viscosity it is one of the most difficult chemicals to handle and also requires ancillary equipment other than regular dosing pump, dosing system and pipings. The DRA chemical when injected into the pipelines helps reduce the frictional loss (between the fluid and pipe wall and within the fluid itself) and also helps in reducing the pressure loss across the pipeline.

Diaphragm Pumps are recommended for hazardous, Toxic and Poisonous liquids, where leakage is not at all permitted. Diaphragm pumps have hydraulically actuated diaphragm and a back pressure valve. The main function of back pressure valve is to balance the hydraulic oil in the chamber. The reciprocating plunger transmit displacement through hydraulic oil to the diaphragm, the oscillation of diaphragm produces pumping action on process fluid with help of Non-Return Valve in built at both ends. The diaphragm acts as a perfect seal between the hydraulic oil and the liquid being pumped. Diaphragm pump can be provided with single or double diaphragm; usually Teflon acts as a diaphragm. The back pressure valve which is in the hydraulic oil tank ensures pumping accuracies for long period. The pressure drop in hydraulic chamber due to oil leakage is automatically compensated by opening back pressure valve. Besides back pressure valve acts as safe guard from damages if discharge pressure exceeds pump rated pressure.
