Heavy duty grout transfer pumps for power station
A construction company contacted North Ridge Pumps recently regarding two grout transfer pumps to be used for a new power plant being built.
Of course, you’ ll probably know what grout is and what it’ s used for. So why is industrial grout any different?
Like domestic grout used in domestic DIY, industrial grout is a composite material usually made of sand, cement and water. It can also include amounts of epoxy resins or other materials to give it greater durability and chemical resistance.
Peristaltic pumps are the ideal choice
Peristaltic pumps are well suited for a variety of construction applications which need abrasive grout to be transferred and injected.
They’ re particularly suitable for projects where the grout transfer pumps may be inoperative for long periods, or when downtime during batches would not be an option.
So why are peristaltic pumps good for transferring grout?
It’ s the simplicity of the peristaltic pump design that makes them ideal for working with abrasive industrial grout. The rough composition of grout and the mix of sand, cement and assorted solids are not a problem for these units. Indeed, they can easily handle a high solids content.
What’ s more, the lack of valves on suction and discharge means there’ s much less chance of the grout transfer pump clogging resulting in costly downtime.
The pumps are easy to use with high suction lift, self-priming capability and very little shear when pumping. In addition, they are easy to maintain should it dry within the pump.
The design is seal-less too and has only one wearing part, so leakage and excessive wear are kept to a minimum. All in all, the pump offers reduced downtime and much less need for regular maintenance.
Which type of peristaltic pump did we specify for this client?
For this construction project requiring abrasive grout transfer up to 15 bar and 3 tonnes an hour, we supplied the client with two of our brand new RBT-40 pumps.
These are shoe-type peristaltic pumps specifically designed to handle high pressures with the hose bathed in lubricant.
Easy maintenance We designed these units to be simple to use and easy to maintain with very little training. In addition, if a hose rupture should take place, we incorporated a built-in leakage detector to stop the pump and prevent leakage.
The two abrasive grout pumps were supplied with a spare set of hoses and sufficient lubricant to ensure that the client had enough spares for at two years of uninterrupted service.
If you have an application which requires the transfer of viscous fluids or dense slurries containing solids, and aren’ t sure which pump to specify, speak to North Ridge Pumps to see how we can assist you.
