The SA-R range of vacuum tankers are premium single axle recessed slurry tankers for farmers and contractors alike. The capacities of the SA-R range from 1350 to 3000 gallons (6,137 to 13,784 litres).  Sizes from 1350 upwards to 2600 come standard on a stepped axle to dramatically lower the overall height of the tanker. HiSpec also use Alliance tyres as standard on these sizes. Alliance tyres are seen as a premium quality radial tyre for heavy-duty field and hauling jobs.

The SA-R tanker range is designed to meets the needs of every farmer and most contractors. Additional features include a swivel hitch, complete with a sprung drawbar for maximum operator comfort. The barrel of the SA-R tankers is recessed to include large radial tyres which provide low rolling resistance, and a greater footprint to reduce soil damage. All of the SA-R range is manufactured using 6mm high quality British steel. Collared dished ends are inserted into the barrel, along with the addition of internal baffle plates and anti-implosion rings to give a strong finish. Unique to HiSpec is the double folded chassis that supports each SA-R tanker in four key areas underneath the barrel. This means that the entire underside of the barrel is fully supported across both the entire width and the length of the tank. This reduces stress on the barrel and helps to minimise weak points.

Stepped Axle

SA-R models from 1350 to 2300 gallons come standard on a stepped high speed commercial axle. This results in the rear of the tanker being lower to the ground than competitor’s models, leading to increased stability and safety on the road or on sloped grounds. The stepped axle is fitted with 420×180 hydraulic brakes as standard to increase stopping power. Air brakes can also be specified to further improve braking efficiency. HiSpec use Alliance wheels as standard on our SA-R range to further improve stability.

Jurop PumpTanker_Pump

A Jurop vacuum pump is fitted as standard across the SA-R tanker range. Jurop is a high quality pump designed and manufactured in a state of the art factory in Italy. Jurop pumps are recognised as the fastest and most powerful vacuum pumps available today. Each pump is assembled according to Jurop’s methodical standards and is carefully tested and checked. PTO driven as standard, Jurop pumps provide the most efficient method of filling or emptying your slurry tank. Jurop pumps have a worldwide reputation for quality and minimal maintenance. Parts and service are available locally from your nearest HiSpec dealer, and the premium build of Jurop pumps ensures an extremely long working life. Additional pump improvement options can be viewed on our Options page.


SA-R models from 1350 to 2300 gallons are fitted standard on 750/70 R26 Alliance tyres (28.1). The unique shoulder design ensures excellent grip and high traction efficiency. The large footprint area reduces ground pressure, minimising compaction and increasing flotation. The 2600 SA-R is fitted on 800/65 R32 Alliance tyres (30.5) (181 A8). These 30.5 tyres are upgraded to 181 A8 rating for use with increased speed or with the addition of a slurry applicator on the rear of the tanker. Strong radial construction with reinforced beads and sidewalls provide long tyre life. The 3000 SA-R is fitted with a straight axle and 750/60 R30.5 Alliance tyres (181 D). Alliance tyres offer higher load/speed ratings when compared with other tyre manufacturers.
