Ebara- 2GPE 3M Industrial booster sets

Ebara- 2GPE 3M Industrial booster sets 

TYPICAL APPLICATIONS


Ebara_2gpe-3m-dimentionThe base of the group is in galvanised steel as are the manifolds. The discharge manifold is set-up to gather any two vertical type membrane reservoirs. Two pressure switches, the electric control panel and a pressure gauge are mounted on it. On suction, each electric pump has
an isolating valve and a non-return valve, with the possibility of connection to an air supply unit and has another isolating valve in discharge mode. The electric control panel is sustained by a relevant support fixed to the base.
TECHNICAL FEATURES
The control panels control pump number one at variable speeds and automatically start any other pumps, allowing to adjust system pressure on constant values. These particulars allow to increase the level of comfort, minimise management costs and reduce all air pre-load
accumulation reservoirs to a minimum.
The typical applications of the GPE range pressure boosters with control panels are:
• Water provisioning for condominium, school, hotel hospital distribution networks etc.
• Water provisioning for industry in general
• Irrigation of gardens, parks and sports fields

FUNCTIONING PRINCIPLES

Ebara_2gpe-3m-Curves• Functioning with PRESSURE-CONTROLLER: the unit responds to the control of the pressure transducer and the speed control via the pump number one inverter, maintaining the system pressure constant
• Double functioning possibility of every pump in AUTOMATIC, MANUAL OR pump EXCLUDED mode
• Pump motors protection against overloads, missing phase over/under voltage
• Pump protection against dry running
• Inverter protection against phase breakdowns, under/over voltage, earth faults, environment overheating
• Functioning of pump number one at variable speed via the inverter; automatic start-up via electro-mechanical contactors of the other pumps
• Automatic switch-over of functioning of pump number one and any other pumps, via electro-mechanical contactors and pressure switches, if the inverter should block
• Automatic switch-over every 24 hours of the powered pumps start-up order via electro-mechanical contactors

Grundfos-DMX Dosing, Diaphragm pump

 

 

Overview

DMX Diaphragm DosingGeneral

The Grundfos DMX range has proven its worth in dosing applications worldwide. With their robust diaphragm-based design and their high-quality motors DMX pumps require minimum maintenance and are best choice for many dosing applications. The DMX range is highly versatile: it covers a wide flow range and offers a variety of dosing head sizes, materials and accessories.

 

Accurate dosing – all the time

The diaphragm design ensures that the dosing flow variation is below ± 1.5 % and the linearity deviation is kept below 4 % at all times. This allows very precise dosing of your chemicals – as much as necessary, as little as possible.

 

Smooth and low-pulsation dosing

The DMX series combines sophisticated drive technolo­gy and gear kinematics to ensure smooth and low-pulsation dosing without pressure peaks. This means less stress to all system components, such as tubes and valves, and leads to longer service intervals for the entire system.

 

Motors to match application needs

WcapsImage-1For applications with specific motor requirements, the versatile DMX range offers high-quality motors for 50 Hz, 60 Hz, 100 Hz (with Variable Frequency Drive VFD), as well as EX classified or ATEX-certified motors, if required.

 

Perfect material selection – for housing and liquid-wetted parts

The smaller DMX models have plastic housings offering chemical resistance and all the protec­tion necessary for many applications. The larger models have a robust cast-aluminium housing with epoxy coating to meet all application needs. Investment costs and running costs for spare parts are kept low over the years: A wide choice of materials for dosing head, valves and accessories allow selecting exactly the degree of chemical resistance required. All liquid-wetted parts need to be resistant to the chemicals used. The diaphragm is made of NBR and PTFE-coated.

 

Compact design – saves money and space

DMX pumps are available in 12 different dosing head sizes. Careful design work has kept them all very compact. This saves material costs and allows placing several pumps right next to each other in confined spaces. Double-head versions (DMX models 226 and 227) offer a very cost-efficient way to save space or to dose two different chemicals. The extra capacity offered by double-head versions can also be used to gain higher flow rates for a single chemical.

 

Screenshot_2Accessories ensure perfect operation of the entire system

A wide range of accessories specially designed for the DMX series help optimise performance: AR control electronics (contact signal control with multiplier and divisor function, 4-20 mA control or stroke frequency control via display and key pad, low-level/empty signal), integrated relief valve, dosing controller, diaphragm leakage detection, servomotor for automatic stroke length adjustment, PTC motors with Variable Frequency Drive (VFD). We also offer system components such as pressure loading valves and pulsation dampers.

Applications

Disinfection, coagulation, flocculation, precipitation, etc. in:

  • Drinking water treatment
  • Waste water treatment
  • Pulp and paper industry
  • Textile industry
  • Cleaning water treatment
  • Food & Beverage industry, dairies
  • Cooling tower water treatment
  • Low-pressure boiler feed water treatment
