Product catalog summary

Overview: The document provides technical specifications and operational details for ELK self-priming centrifugal pumps, specifically the TMA G1 model, manufactured in Italy. These pumps are designed for handling chemical liquids with high specific gravity and vapor tension, suitable for various industrial applications.

Specifications:

Self-priming capability with a maximum lift of -5 meters.
Reversible inlet and outlet by changing motor rotation direction.
Suitable for liquids with specific gravity up to 2 kg/dm³ and vapor pressure up to 1 meter (H₂O at 45°C).
Minimum NPSHa of 3 meters (absolute).
Compatible with IEC or NEMA standard motors.

Benefits:

Constructed with stainless steel base and trolley options.
Available with check valve and foot strainer made of PP or PVDF.
Dispenser nozzle options in PP or PVDF.

Accessories: Includes a trolley made of AISI 316 with an electric device, and pumps made of ECTFE+carbon with strong magnetic coupling options for different specific gravities.

Performance: The document includes performance curves showing power, capacity, head, and efficiency at different RPMs (2900 rpm - 50Hz and 3500 rpm - 60Hz).

Technical Data:

Models 01.16 and 01.21 with power options ranging from 0.55 kW to 1.1 kW.
Motor specifications include IEC frame, phase, voltage, frequency, and protection ratings.

Materials and Temperature:

Volute casing and other components made from GFR-PP, CFF-E-CTFE, and other materials.
Temperature ranges for different versions: WR (-5°C to 80°C), GF (-20°C to 100°C).

ATEX Compliance: The pumps are approved for explosive atmospheres as per ATEX directive, suitable for Cat. 2 Zone 1 environments.

Working Principle: The pump operates through a priming phase, pumping phase, and stopping phase, ensuring efficient liquid movement.

Applications: Suitable for chemical, agricultural, seawater, and wastewater applications, among others.

Example Installations: ELK G1 pumps are used in power plants for electrochlorination equipment during cleaning phases.

SELF-PRIMING PUMPS This peripheral pump is a product between the displacement and the centrifugal pump, in which the medium is pumped in a peripheral channel. It can operate with inlet and outlet reversible by reversing the direction of motor rotation and are adequate to suck up chemical liquids with high specific gravity and/or high vapour tension. PERFORMANCE Strong magnetic coupling made up of rare-earth ELK pump made of ECTFE+carbon materials (Neodimium Iron Boron) and “N” (standard), “P” (powered) or “S” (strong-powered) versions allow to pump, also at maximum flow, liquids with 1.05 - 1.35...

WORKING PRINCIPLE Stopping phase: a small quantity of liquid is trapped into the pump to enable the next starting. Priming phase: the impeller gives a specific circulation of air-liquid mixture moving air from the suction pipe to the discharge side in the atmosphere. Pumping phase: after the air is totally removed from the suction side, the pipe is flooded by the liquid and the pumping phase can start. APPLICATIONS ELK pumps are ideal for applications requiring a reversible flow and service operations, used in the following sectors: • Chemical industry (acids, cleaning solutions, inks,...) •...
