Technical Data

S Series Twin Screw Pumps With Timing Gear (WTG)

Self-priming, double-suction twin screw pumps using timing gear transmission and exterior bearings. They work particularly well for delivering fluids that are either barely abrasive or devoid of particulates.

Low noise
No emulsified shear
Low pulsation
Suitable for wide range of viscosities
No fluid agitation
Direct drive
Overload protection
Reliable

S Series Twin Screw Pumps With Non-Timing Gear (NTG)

A single-suction design that adjusts for axial pressure on the hydraulic components using a balancing piston. There is metal-to-metal contact between the casing bore and screw profiles. Bitumen and residual oil, which have higher viscosities, can be transferred with these pumps at medium or high temperatures.

Low noise
No emulsified shear
Low pulsation
Suitable for wide range of viscosities
Low fluid agitation
Direct drive

S Series Multi-Phase Twin Screw Pumps

Multi-phase twin screw pumps are long-lasting, dependable, and strong, and they are made for medium- to low-pressure applications in the commercial maritime and oil and gas industries. These pumps, which were made for applications requiring higher suction and differential pressures, are frequently utilized in oilfields with untreated streams.
