The basic principle of the peristaltic pump traces back to human “peristalsis” a term referring to the alternating contraction and relaxation of muscles around a tube to force the contents through it.An elastomeric tube is squeezed along a length by rollers that push the fluid contained within. The tube’s restitution after squeezing produces a vacuum that draws fluid continuously into the tube.

This creates a gentle pumping action that doesn’t cause any damage to the product. Contaminations are avoided because the fluid is contained within the tube (one contact part with product).The pump employs a rotor with rollers mounted on it that continually compress and occlude some portion of the tube. This action moves the fluid through the tube with a constant rate of displacement for each revolution of the rotor, enabling a precise measurement of the volume of fluid pumped through the tube.

The MONIBA ANAND PUMP

The “roller on bearings” design of the Moniba anand pump offers many advantages:

It eliminates the requirement for adding a lubrication fluid inside the pump housing, because there is no friction on the surface of the tube therefore giving a longer tube life.
They can transfer food products with no con tamination hazards, as the pump housing is lubrication free.
With no lubrication fluid required, hose replacement is greatly simplified and cheaper without having to drain and dispose of a messy and possibly contaminated oil or glycerine solution.

How the pump Works

Left stroke

The air valve directs pressurized air to the back side of diaphragm A. The compressed air is applied directly to the liquid column separated by elastomeric diaphragms. The diaphragm acts as a separation membrane between the compressed air and liquid, balancing the load and removing mechanical stress from the diaphragm. The compressed air moves the diaphragm away from the center block of the pump. The opposite diaphragm is pulled in by the shaft connected to the pressurized diaphragm. Diaphragm B is on its suction stroke; air behind the diaphragm has been forced out to the atmosphere through the exhaust port of the pump.
The movement of diaphragm B toward the center block of the pump creates a vacuum within chamber B. Atmospheric pressure forces fluid into the inlet manifold forcing the inlet valve ball off its seat. Liquid is free to move past the inlet valve ball and fill the liquid chamber (see shaded area).

mid stroke

When the pressurised diaphragm, diaphragm A, reaches the limit of its discharge stroke, the air valve redirects pressurised air to the back side of diaphragm B. The pressurised air forces diaphragm B away from the center block while pulling diaphragm A to the center block.
Diaphragm B is now on its discharge stroke. Diaphragm B forces the inlet valve ball onto its seat due to the hydraulic forces developed in the liquid chamber and manifold of the pump. These same hydraulic forces lift the discharge valve ball off its seat, while the opposite discharge valve ball is forced onto its seat, forcing fluid to flow through the pump discharge. The movement of diaphragm A toward the center block of the pump creates a vacuum within liquid chamber A. Atmospheric pressure forces fluid into the inlet manifold of the pump. The inlet valve ball is forced off its seat allowing the fluid being pumped to fill the liquid chamber.

right stroke

At completion of the stroke, the air valve again redirects air to the back side of diaphragm A, which starts diaphragm B on its exhaust stroke. As the pump reaches its original starting point, each diaphragm has gone through one exhaust and one discharge stroke. This constitutes one complete pumping cycle. The pump may take several cycles to completely prime depending on the conditions of the application.

Internal Flow

The pumpage is taken from the discharge side of the impeller and fed back through the inner magnet, the isolation shell and the prod act wetted bearings to both cool and lubricate the drive assembly.

The recirculation flow for any Magnetic Drive pump has three basic functions

Removal of the heat generated from magnetic losses;
Lubrication of the internal radial & thrust bearings;
Thrust balancling of the free floating matting assembly

To successfully meet these requirements, the circulated pumpage most remain in the liquid phase at all points within the magnetic coupling area.
 

Cartridge Replacements

The low cost alternative to a standby pump
On site installation is straight forward using your own staff
Your used cartridge can be refurbished & returned
Cartridge replacements keep your spares inventory low
Cost effective standby for multi pump installations
Replacement cartridge fully complies with original pump specification, ensuring maximum integrity

There has never been a more cost effective way to keep plant inventory at a manageable level than with a MONIBA replacement cartridge. As a spare part it is both easy to install and more importantly completely complies with the original technical specifications of your pump. The complete rotating unit is replaced thus assuring the total operational integrity of the pump. Most cartridges can be replaced in less than one hour, keeping downtime and lost production to a minimum.

Features

Moniba Heavy duty pumps are equipped with outstanding features that guarantee advanced performance over less durable pumps, with pioneering construction that allows for total operation in fully, part or non-submerged conditions.

Double Out Let Casing

1-Double casing balance the flow.
2-Life of pump will be more.
3-Pump operation will be smooth

Moniba use a 'Twin Volute' casing which puts a balanced load on the shaft which leads to much longer mechanical seal and bearing life as standard.

Competitors 'Single Volute' casing puts an uneven load on the Shaft, which often leads to premature mechanical seal and bearing failure .

Inducer Effect

The Inducer sends hydrodynamic shock waves below the pump which makes settled Solids start to flow
The patented Moniba Inducer sends hydrodynamic shock waves below the pump which makes settled solids start to flow.

Canned Motor Pump is a combination of a centrifugal pump and an induction motor presented as an integral unit. In the canned motor Configuration the motor is mounted directly on the same shaft as the impeller.
Canned pumps are of simple design and construction, having very few parts and only two rotating parts-rotor and the impeller.
Secondary sealing is restricted to a couple of static gasket, which are again well confined.
Canned pumps do not required any external lubrication.
Canned pump is seal less and auxiliary support arrangements for cooling seals are not required.
Bush Bearings made out of carbon graphite and silicon carbide are the only parts that come up for replacement and the bearing have a very long life since there is no load on bearings, because of automatic thrust balancing, inherent in the design.
Canned pumps runs with negligible vibrations (<10 microns) and thereby wear and tear is greatly diminished.
Maintenance and operational cost are negligible compared  to conventional pump.
CANNED PUMPS NEVER LEAK – on continuous  or intermittent pumping or even in case of pump failure.
MONIBA PUMPS are certified FLAME PROOF/EXPLOSION PROOF (EEx-d IIB T6 (Ex) ds.).
Conform to AP1685, 1st edition for petroleum application.
Approved by leading consultancy in India.
Catering to wide range of service & duty conditions.
Available in all possible verity of construction.
Although the initial cost of canned pump is higher in comparison with conventional pumps, the advantages it offers – flawless pumping; minimum maintenance; negligible spares replacement; no hazards – contributes to definite cost-benefits, if the operating costs are computed even over 2-3 years time. Canned pumps will thereafter, prove tremendous economy in operation considering the minimum 15-20 year life cycle of the pump.
