First reliable mechanical extractor used to collect maple sap.
|1976||First to introduce a SIHI water cooled vacuum pump in the maple syrup industry.|
|1976||First plastic mechanical extractor in service. Thus rustproof, durable, and affordable.|
First vertical transfer tank. The concept is to maintain vacuum on longer distances separating water and air to increase efficiency.
|1986||Conception of a vacuum regulator allowing an easier regularity throughout the system.|
|1986||Self sufficient pumping stations combining vacuum pump and water pump to a gas or diesel engine thus eliminating the use of electricity.|
Pressure control invented to automatically adjust pressure inside collectors during washing.
|1986||Practical collector for the Zero type vacuum tank.|
|1987||Development of an R.O. really adapted to the maple industry. With it’s individual and efficient recirculation system, this system was able to operate all day without cleaning or rinsing.|
|1987||Developing storage canisters conceived to transport and protect membranes during the off season.|
|1989||Developing the Sirofiltre-Lapierre (Cylindrical syrup filter) allowing reducing cleaning and filter changing to less than a minute.|
Efficient, user friendly and portable, it is still very popular today.
|1991||Appearance of the large capacity Lapierre cylindrical filter conceived to pre-filter sap before the concentrator membranes.|
|1991||Development of a horizontal extractor series just as efficient as the vertical but easier to clean.|
|1994||Improvement of the pressure control used for tubing cleaning in order to optimize the precision and durability of the equipment.|
|1994||Development of a moisture trap designed to protect oil cooled pumps from water damage.|
|1996||Development of a new family of turbine driven over-pressure pumps designed for various apps. Simple and quiet, those were an instant success.|
|1996||Development of a vacuum power sap piston pump. Designed to pump sap on long distance reverse slopes without electricity.|
|1996||Development of a vacuum control for high output pumps.|
|1996||Development of an automatic water pump starter control to use inside sap tanks.|
|1997||Creation of a new R.O. line driven by Lapierre high output turbine pumps.|
|2005||Electrical pneumatic extractor affording the possibility of out of extractor pumping at high vacuum levels.|
|2006||Development of a sap lifter ; an excellent alternative to sap ladder used for reverse slope.|
|2007||Development of the first mechanical extractor designed for smaller operations. The Hobby 500 is made for 500 taps or less.|
|2007||Development of an R.O. membrane horizontal support facilitating the job, operation and maintenance while reducing the space needed for the reverse osmosis room.|
|2008||Development of the Lapierre Junior R.O. created for small operations; two (2) models available being 100 gph and 200 gph.|
Year in and year out Donald Lapierre has conceived fitting for the maple industry such as the slide fitting and the elbow hook for end-line.
Also, since the merge with Waterloo Small several innovations have been brought forth on the evaporators such as the universal pans,
