SA – Bareshaft Pump
Robust & Heavy Duty Pumps With encapsulated Cardan Joint
The SA Progressive cavity pump is constructed with Bareshaft Design. This gives a lot of flexibility in Drive configurations. nit is mounted directly onto the Pump Body without the need of any couplings. All ROTOMAC SD pumps can be used in almost all industrial sectors and suited for low-viscous to viscous media with and without solids.
Capacity: 0.1–400 m³/h
Pressure: ≤ 36 bar

Options
Tech
- Discharge Port:
Available with Gauge Connection, Flange Connections conforming to ISO, DIN & ANSI standards.
- Rotor:
Wear resistant and corrosion-resistant materials. Optionally with hard surface treatment.
- Conventional Geometry :
With Shorter Pitches the geometry is for high Pressure applications. - Extended Geometry:
With a Small rotor diameter and a long pitch, the Extended geometry attains lower surface velocities and extends the service life due to its large sealing line. - Stator:
The seal on both ends is molded as an integral part of the elastomeric stator. - Suction Housing:
With large cross section and designed for smooth flow conditions, with drain plug and connections for pressure/vacuum gauge. Flange connections in DIN or ANSI can be rotated in 90° increments. - Robust Cardan Type Joint:
Heavy Duty, Robust , Long Lasting Cardan Type Universal Joint , it can handle more load due to its inherent design. These joints offer a longer service life than the conventional Pin joint.
- Yoke Shaft:
Connects the drive shaft to the joint. With gland packing the plug-in shaft is used as a shaft protection sleeve. Upon request, it is available with wear resistant coating
- Shaft Sealing:
Available in Gland Packing and also with Flushing lantern Ring , Single Mechanical seal as well as Double Mechanical seals
- Close Coupled Drive Connection:
For easy dismantling of the pump and drive enabling quick replacement of the rotating parts and shaft seals. The yoke shaft pin secures the shaft connection to the drive and the Water Thrower protects the drive from contamination/gland leakage.
- Body:
For connection of pump and drive and to secure the assembly to the baseplate or directly to the foundation.
- Drive: Geared motors, variable speed drives or frequency controlled motors of all major manufacturers, directly flanged to the pump without additional couplings or guards. Covers made of stainless steel are available.
Accessories
- Dry Run Protection:
Dry Run protection monitors the temperature of the stator and shots the pump down when the limit value is reached to protect the pump from dry running.
- Overpressure Protection:
The pressure gauge switches off the pump as soon as a pre-set pressure is exceeded or not reached and protects the pump from increased wear and tear or piping damage.
- Seal Support Systems:
We offer seal Flush, Quench, Barrier type support systems. barrier type systems protects the shaft sealing by selectively supplying barrier liquid. Also available with flow meter on request.
- Retensioning Device:
With this device, a worn stator can be evenly readjusted at several points so that the clamping between the rotor and stator is once again optimal and the pump performance increases.
Options
- Standard Baseplate:
Suited Basepalte For Mounting With Geared Motor, For Standard Applciations , Specialized Features Available As Per Custom Requirements - SEALING OPTIONS:
- Standard Gland Packing:
Universal seal for hopper and standard pumps for sealing the plug-in shaft and suction casing or feed hopper. Also available with grease or lantern ring to shut off the media flow. Can also be supplied with upstream labyrinth seal and additional flush connection or lubricating device. - Multiple Acting Mechanical Seal:
Mechanical seals arranged in a row. Available in “back-to-back”, “face-to-face” or “tandem” sequence
- Standard Gland Packing:
- Cartridge Mechanical Seal
