Special pump for thicker grout mixes in
boreholes
Mono Pumps have enabled geo-thermal drilling specialists Sintec Environmental to meet EA requirements for sealing bore-holes while still investigating geo-thermal heat sources
Mono Pumps have enabled geo-thermal drilling specialists Sintec Environmental to get on the move with their new mobile site support system Sintec, a northern company based in Lancashire, specialise in geo-thermal drilling, and installing and grouting of ground source vertical and horizontal heat sources, for heat pump installations

Further improvement to manufacturing processes enables Mono Pumps to pass cost savings to customers in the food, chemical and pharmaceutical industries with the Hygienic S Range pumps.
New Mono coating provides answer to rotor abrasion
Mono Pumps, a leading manufacturer of pumps and pumping solutions, has launched Duracoat 3000 - a new surface coating offering increased wear resistance for rotors used in highly abrasive environments
They have designed and manufactured a multipurpose trailer which can mix and inject grouting media or alternative products into chosen cavities, anywhere on site.
The Mono Widethroat W range pump forms an essential part of the Sintec mobile system by pumping the thicker grout mixes more quickly and efficiently.
Once the mobile system is in-situ and drilling of an exploratory hole is almost complete, a mixer combines the bentonite/cement grouts to form bentonite slurry.

Solution to corrosion for Northumbrian Water
An unexpectedly high levels of corrosion was at the root of problems with two centrifuge cake disposal pumps, which needed frequent visits by maintenance staff at Honeyhill Water Treatment Works
This is then transferred by the W Range pump to the holding tank ready for injection into the hole within a matter of minutes.
A lean mix of bentonite and cement is the standard site investigation mix and is designed to stop any cross contamination of aquifers.
The Widethroat W range pump is ideal for this type of application as the pump has been designed with an enlarged, rectangular inlet and screw conveyor to assist thick slurries into the pumping element for easy transfer.
The rotary action of the positive displacement pump generates pressure at any speed and does not require centrifugal force or high rotational speeds to operate.
As the pump does not rely on any centrifugal action for its operation, there are no large changes in fluid velocity.
Agitation and turbulence are therefore minimal, and shear sensitive products can be pumped without damage.
The Widethroat pump design is a good choice for delivering a steady flow of viscous materials, which benefit from the slow running speeds and gentle handling made possible by the progressing cavity pump action.
The Environment Agency is endeavoring to enforce legislation such as section 86 of the Water Resources Act 1991 which expects that possible pathways of contamination of existing boreholes, which have been sampled and monitored, will be sealed up.
With the new Sintec mobile support system, comprising mixer, pumps, necessary pipework and holding tanks, water pressure testing system for geo-loop installations, pressure grouting attachment for the back fill of existing installations and hydraulic power take off to run jack hammers, concrete corers and geo-loop installations, you have the complete system.
