RHINO-Argal

Product catalog summary

Overview: The document provides detailed technical specifications and operational guidelines for RHINO self-priming centrifugal pumps, specifically the TMA G2 model. These pumps are designed for high efficiency in handling various chemical liquids, including those with high density and viscosity.

Specifications: RHINO pumps feature a biphasic impeller that allows for fast priming and high suction head capabilities. They are constructed from chemically resistant materials such as PP and E-CTFE, making them suitable for corrosive liquids. The pumps can handle a maximum lift of -6 meters and specific gravity up to 2 kg/dm3.

Performance: The pumps are equipped with a strong magnetic coupling using rare-earth materials, available in different power versions to accommodate liquids with varying specific gravities. The biphasic impeller design enables the pumps to prime from an empty suction pipe, making them efficient for both high-density and high vapor pressure fluids.

Motor Specifications: The pumps are compatible with standard IEC or NEMA motors and are available with stainless steel bases and trolleys. They are also ATEX certified for use in explosive atmospheres, with specific models approved for Cat. 2 Zone 1 environments.

Applications: RHINO pumps are ideal for use in the chemical, mining, power, food and beverage, and pulp and paper industries. They are particularly effective for operations involving negative suction aspiration and the transfer of heavy liquids.

Installation and Operation: The document outlines the working principle of the pumps, including the priming, pumping, and stopping phases. It highlights the importance of trapping a small quantity of liquid in the pump to facilitate the next start.

Technical Data: The document includes detailed technical data, such as power requirements, motor specifications, and temperature ranges for different pump versions. It also provides performance curves illustrating head, efficiency, and power relative to capacity.

BENEFITS • Choice of material chemically resistant to all corrosive liquid • Ability to prime from an empty suction • Fast priming • Magnetic core embedded in the biphasic impeller • Max. lift = -6 m • Max. allowed specific gravity up to 2 kg/dm3 • Minimum NPSHa = 3 m (abs) • Standard motors IEC or NEMA. Thanks to its construction, RHINO pumps develop a higher suction head and shorter priming time than the traditional self-priming centrifugal pumps; the biphasic impeller primes fluids with high density, viscosity and vapour such as sulphuric 98%, hydrochloric 33%, nitric, phosphoric acids, sodium...

INSTALLATIONS 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 RHINO pumps are ideal for negative suction aspiration operations from a basement tank to truck or surface tank, for unloading and transferring waste collecting wells...
