PDP SCREW PUMPS are employed for a great diversity of purposes including conveyance of heavy oils, lube oil service, pressure delivery as well as for hydraulic applications.
CONSTRUCTION AND PRINCIPLE
The PDP-SCREW PUMP is a constant placement, rotary, screw type pump having a very simple construction. It has only three moving parts, i.e., a power rotor and two idler rotors, and fluid is propelled axially in a constant flow through these three rotors.
The three rotors mesh smoothly and perfectly inside sleeve. The idler rotors turn by action of fluid pumped and act as sealing element since idler rotors perform no work, rotors need not be connected by gears for power transmission.
The sealed closures formed by meshing of rotors within sleeve enfold fluid being pumped. As the rotors turn, these closures move axially, providing a continuous smooth flow of the fluid without causing any churning.
The thrust force generated by delivery pressure imposes no load on the pumping frame. This is because oil pressure is balanced at all times by patented oil hydraulic balancing construction.
FEATURES
QUIET
The smooth rolling sound of SCREW PUMP is smaller than sound given by driving electric motor. The pump body registers a noise level of 63 ~ 68 dB (A) at working pressure of 24.5 MPa (250 kgf/cm2), and this is not at all jarring because of its low frequency range.
LOW-PULSATING FLOW
Fluid delivery is continuous, and pulsation or churning is very small.
DURABILITY
Complete absence of power transmission between the power rotor and the idler rotors minimized the wear of the rotors, providing them with good durability. The pump is free from troubles due to wear because it requires no gears for power transmission, sliding vanes or cams.
HIGH SPEED
Because of small diameter of its rotors, the pump can be run at high speed so that its capacity is quite large compared to other types of pump.
HIGH SUCTION LIFT
Fluid is propelled axially without being churned at the suction inlet. This factor provides excellent suction lift capabilities and makes the pump compatible with high viscosity fluids.
APPLICABLE TO VARIOUS FLUIDS
Owing to the unique construction and principle, the screw pump is applicable to various fluids. For the detailed information about the fluid and pump series.
