POSIBLE INSTALLATIONS

Our peristaltic pumps with accessories can be used for many applications and are not restricted to a specific installation location. Fixed installation directly into the process flow is possible, as is the use as mobile or portable unit that can be transported to different applications. The standard version of the pump set-up is the combination: ports on left-hand side (suction side top - pressure side bottom, red).

Of course, the IP series peristaltic pumps may be adapted to existing installations by modification of the port configuration. This only requires the relocation of the stainless steel pipe connections on the suction and discharge side of the vacuum system to suit the desired condition. This can be done without additional machining.

OPERATION OF SERIES IP

	A - The rotor rotates within the pump housing filled with lubricant and compresses the pumping hose with the sliding shoe (1). This process generates a hermetic separation between suction and discharge side.
	B - Once the second sliding shoe (2) compresses the hose, a completely enclosed pumping chamber is formed. This volume corresponds exactly to half the pump capacity per rotation. A vacuum is also generated inside the pump housing, supporting the elasticity of the hose allowing restoration to its original full cross-section.
	C - The rotation of the rotor forces the pumped medium inside the hose towards the outlet port on the discharge side. During each opening of the hose a vacuum is created on the suction side ensuring constant suction. It also takes place when the hose is empty giving high suction conditions.
	D - With each rotation the pumping chamber is reformed and the suction capability is renewed.

OPERATION OF SERIES M 300

	A - The rotor turns inside the tightly fixed separator. Which is held in the pump housing filled with lubricant. The separator divides the housing into two completely enclosed areas. This means during compression of the pumping hose the suction and discharge sides are hermetically separated.
	B - Air from the suction side is pumped over the separator by the turning of the rotor and exhausted outside the pump. This forms a vacuum inside the pump chamber relative to the suction lift, which supports the elasticity of the hose during restoration to its original full cross-section.
	C - Once the second sliding shoe compresses the hose, a pumping chamber is formed. This volume corresponds exactly to one-third of the pump capacity per rotation. The rotation of the rotor presses the medium inside the hose towards the outlet on the discharge side. During each opening of the hose a vacuum is created on the suction side ensuring constant suction. It also takes place when the hose is empty giving high suction lift conditions.
	D - With each rotation the pumping chamber is reformed and the suction capability is renewed.

SELECTION, PUMP CAPACITY

For the selection of the mobile ELRO
Peristaltic pumps series M300, the following factors are to be considered:
• pumping medium
• pumping capacity
• suction and discharge conditions
• operation time per day
• location of use
• accessories with suitable couplings

The essential items for a low-wear operation of the peristaltic pumps are dependant on:
pumping media <=> speed
media temp. <=> hose compression
discharge pressure <=> Consider larger diameter discharge lines
operation time per day <=> continuous intermittent short time

After fixing the operation point, depending on the above parameters, an exact specification of the pump can be made using the individual data sheets. Using the selection diagram, adjustments may be necessary after consideration of the factors "Operation time/day and media temperature".

At a media temperature >40ºC, hose life is shortened and a speed reduction should be considered.

• Short-time operation (max. 4 hours)
• Intermittent operation (max. 12 hours)
• Continuous operation (24 hours)

For further details see our separate compatability guide.

For special applications, special full fabric hoses are available for the series IP.

Peristaltic pumps can be equipped with a suitable pumping hose for almost any application.
The great variety of different hose materials results from intensive research and long-term tests.

All pumping hoses are precision ground after the production process. This additional process ensures an uniform surface and a constant outside diameter compared with conventional hoses.
It prolongs hose life and in addition, a consistent pump capacity is achieved for all pumps.

HOUSING MATERIAL

The pump housings of the ELRO peristaltic pumps are cast from aluminium. This process which is more complicated than steel casting or welded designs is used for the following reasons:
• better heat dissipation
• integration of cooling ribs
• air tight housing
• reduction of wall thickness
• compact construction
• wear resistant
• low weight

PERISTALTIC PUMPS
SERIES IP

The IP series of ELRO peristaltic pumps distinguish themselves through a gentle transport of liquid or viscous media. Also capable of handling abrasive, shear-sensitive products with long fibres and solids.
Over the years they have become an integral part in the pump pool of many operators. The 13 bar pump pressures of the standard versions make ELRO peristaltic pumps suitable for replacing other pump technologies. The seven pump sizes, various hose materials including food approved versions and the different port options allow individual adaptation to each application. This variety is further expanded by the frame and motor variants.

Peristaltic pumps are equipped as a standard with a patented vacuum system. It leads to many economic and technical advantages such as:
• very good suction properties up to 9.5 m lift (no additional suction equipment required)
• constant pump capacity during the entire hose life
• enables the hose to reform to its full cross section
• low reduction in capacity when handling very
viscous media
• use as early warning system for a just in time
hose exchange

APPLICATIONS   Main application: • Chemical industry • Ceramic and porcelain industry • Building industry • Food and beverage industry • Breweries • Cosmetic and pharmaceutical industry • Power stations • Colour and painting industry • Waste and disposal industry The patented early warning system (see illustration right 2, 3) works as follows: Each hose is provided with a small additional channel through which the air in the upper section of the pumping chamber is evaquated from the pump housing. Therefore, a vacuum is formed in the sealed aluminium housing. In the case of damage or normal wear of the hose, the vacuum will drop. The early warning can be seen through the installed vacuum gauge. An acoustic or optical signal can be activated by using the vacuum switch 1. By this, the hose condition is monitored for optimum service planning. Downtimes through normal wear can be predicted.

SERIES IP

The IP series of ELRO peristaltic pumps are available with a variety of accessories for each application.

1. Flanges in steel, stainless steel and plastic according to different standards
2. Compensators in steel, stainless steel with matched elastomer materials

SERIES M300

M300 series Peristaltic Pumps were designed for safe, quick and mobile applications in the most varied industrial operating conditions. Over many years this unique, patented pump system has been and is successfully used world-wide for more and more new applications.

The basic idea during the development of the mobile peristaltic pumps was to integrate the advantages of standard peristaltic pumps and to achieve a compact, portable and flexible design. This idea was realised through a special, patented concept in the pump housing design.

Main Application: • Environmental technology • Tank cleaning • Building industry • Chemical industry • Forwarders • Power stations, disposal technology • Ships, port facilities and skimmer The peristaltic pumps can be equipped with different hose materials depending on applications as well as with couplings on the suction and discharge side in different materials and designs. The M300 series can be selected with a variety of different motors. For special applications, the pump is also available in a reversible design. Therefore it is possible to pump in the opposite direction with the same performance features - a decisive criterion when pumping out and pumping over media which are harmful to the environment. The design of all pumps enables changing of pumping hose and all components within shortest period of time without any additional special tools.
