• The air, which is forced out, is not allowed to come back due to the small internal clearance within the internals of the machine, except a very small amount (SLIP). There is no change in the volume of the air within the machine, but it merely displaces the air from the suction end to the discharge end, against the discharge system resistance i.e., no compression takes place in the machine. Since the lobes run within the casing with finite clearances, no internal lubrication is required. The air, thus, delivered is 100 per cent oil free. These blowers deliver, practically, a constant flow rate independent of the discharge pressure conditions. The flow rate is dependent, largely on the operating speed.

Due to these constructional features, it has the following distinct characteristics:

• Flow largely depends on operating speed.
• The input power is largely dependent on the total pressure across the machine.
• The suction and discharge pressures are determined by the system conditions.
• The temperature rise of the discharge air and machine largely depends on the ƒ¢p across it.

Scope Of Supply:

Base Plate frame

For mounting all system components

Powder-coated according to RAL 9003 (signal white)

THREE pumps are mounted on shelves one above the other. This allows a small footprint of the system.

Slide out shelves and gallows for chain block support for easy handling and maintenance, thus the pumps can be handled by one person without any problem

Interlock system to the shelves for a high safety level (prevents system from toppling).

For connection to the pipe network, the vacuum and exhaust connections of the pumps are manifold to one connection for each.

On the suction side each pump is equipped with a shut-off-valve

Two valves to connect two plate base frame and for connecting to a vessel Flexible connection hose for suction and exhaust air

No foundation is required for installation and bolting to the floor is not necessary.

Constant Vacuum Valve: As an 2/2 way solenoid valve to keep the pressure constant and to avoid frequent on- off switching of the Vacuum pumps.

Room Temperature Switch : To issue a warning if the room temperature exceeds 50 degC

Halward offers Dry Screw Oil free Vacuum pumps by Elmo Rietschle.

Two parallel bearing-supported, intermeshing screw rotors (3) having opposite threads synchronously and contactlessly counter-rotate in a cylindrical housing (2) that tightly encloses them, and together form a multi-stage pump. Because of the counter-mesh of the two rotors, the volumes sealed in each thread are advanced along the rotors to the outlet (4). The pump has no valves at either the inlet (1) or the outlet. When a displacement volume reaches the outlet opening, the pressure is equalized with the atmosphere. This means that atmospheric air flows into the displacement volume and is then discharged again as the rotor turns. This pulsing gas flow generates a high level of dissipated energy and heats the pump. The dissipated energy can be minimized by means of internal compression. This internal compression is achieved by reducing the thread pitch in the direction of the outlet. The gaps between the housing and the rotors, as well as between the rotors relative to one another, determine the ultimate pressure which a screw pump can attain. The geometry and the gap configuration which results when the rotors engage with each other also significantly influence the ultimate pressure. Because the dissipated energy that is generated by the pulsing gas flow heats the pump on the outlet side, cooling is required at precisely this location. The gap between housing and rotors is a function of the temperature differential between the warmer rotors and the cooled housing. The amount of heat produced and the temperature are a function of the inlet pressure range. Temperatures are lowest at high inlet pressures (nearly atmospheric), as virtually no compression work is performed here and the displaced air transports sufficient heat out of the pump. In addition, the high gas flow also prevents oscillation of the gas in the last stage. During operation at ultimate pressure (p < 1 hPa), the oscillation of the atmospheric air produces higher temperatures at the outlet area, since no gas is passing through the pump and therefore no heat is being transported out of the pump. Hepta Dry pumps are dry screw pumps with internal compression. The screw rotors have a symmetrical geometry with variable pitch. These pumps do not have an end plate with control openings; instead, the gas is discharged axially against atmospheric pressure. Because of the internal compression, the volume of pulsing gas is low. This results in lower power consumption, quiet operating, uniform temperature distribution within the pump and low cooling water consumption. This makes these pumps extremely cost-effective, in spite of their robust design.

Halward offer Indigeneously manufactured as well as imported Robuschie (Gardner Denver) make Tri Lobe Blowers from Italy.

Gardner Denver is shaping the standards of performance and reliability in the design of positive displacement blowers and vacuum pumps. The tradition continues with the TriFlow Series vacuum pumps. Each TriFlow is engineered for a wide range of commercial and industrial applications. Specifically, TriFlow is the choice of leading Original Equipment Manufacturers (OEMs) of truck mounted vacuum cleaning systems.

TriFlow offers operators significant benefits and advantages:

• Great performance and efficiency in a compact design 
• Quiet operation 
• Highest quality materials and construction 
• Flexible installation capability 
• Reduced maintenance 
• Available in 3 sizes – 406, 408 & 410 
• TriFlow delivers.

• Three lobe impeller geometry allows higher throughput while creating lower pulsation levels than two lobe units, resulting in reduced noise 
• An internal feedback porting arrangement contributes to the further reduction of noise.

• Backed by one of the largest distributor networks in the industry.
• Every TriFlow vacuum pump is built under rigid ISO 9001:2000 quality standards.
• Each TriFlow is individually tested to meet rigorous performance specifications.

• 18 months from the date of shipment or 
• 12 months from the date of installation, whichever occurs first.

• Highly reliable Dual Splash Lubrication 
• Heavy duty bearings 
• High strength timing gears 
• Integral heat dissipation fins on the case to help maintain proper clearances.

• Piston ring seals are incorporated on each impeller shaft with a lip seal on the drive shaft, providing superior sealing to prevent oil leakage into the air chamber.
• Independent oil sumps prevent cross contamination and allow the vacuum pump to operate safely on an incline when used in carpet cleaning applications.

• Unique, integral mounting surfaces are precision machined for ease of installation and drive system alignment.
• Critical mounting dimensions are similar to those of existing two lobe positive displacement vacuum pumps allowing for system upgrades.
• The inlet and outlet ports include both flange and FNPT connections for ease of plumbing.
