| General |
Designed to automatically meter, mix and pump two component, 1:1 ratio epoxy polymer adhesives in 5-gallon pails using air-driven components only. Eliminates off-ratio mixes and produces a controlled bead or flow rate for surface seals, large crack injection, and filling of slots, grooves and structural bolt or rebar anchors |
| Design |
4 wheel aluminum frame cart, with capacity to hold two-5 gallon
pails for two component paste adhesives |
| Materials of construction |
Welded aluminum frame, wood base |
| Dimensions |
Height = 42", Width = 30", Length = 18" |
| Weight |
45 lbs dry weight |
| Air controls |
Mounted on rear panel are pump piston control valves and regulators, vacuum bleed valve, shuttle valve, and air logic valves. Pump will cease operation unless both component pistons are within one stroke of each other |
| Air Motor speed |
Variable, from 0 to 145 c.p.m., controlled by pressure regulator |
| Speed & Flow Control |
Automatic by pressurer |
| Pump ON/OFF control |
Automatic pressure switch, set by operator |
| Noise level @ 120 p.s.i. |
< 85 d.b.a. |
| Pumps |
2 Lincoln 50:1 Air motor driven with PTFE seals |
| Pump support cylinder |
Carries pump yoke and is raised and lowered by auxiliary air controls to position follower plates in pails |
| Stroke valves |
Attached to air logic controller—assure that 1:1 ratio is maintained. If either pump fails to complete a stroke, the air logic shuts down complete pump operation. |
| On/off control valve |
A remote valve controls paste pump operation from the work face with 20' of dual air line. |
| Mix Ratio |
1:1 by volume |
| Ratio accuracy |
+/- 5% maximum error @ a 5 gallon/hour flow rate |
| Pumping pressure |
0 to 7500 p.s.i. range |
| Pressure Control |
Automatic pressure switch set by operator |
| Delivery rate |
0 to 25 gallons of mixed paste adhesive per hour |
| Delivery hoses |
25 ft. in length, SAE type 100R7 with burst pressure rating of 11,000 p.s.i. |
| Mix head |
Aluminum body with three tandem mix chambers containing replaceable mix elements
Fitted with operator control valve |
| Special features |
Elastomeric pail wipers back stainless steel follower plates that scrape buckets clean on sides and prevent pump cavitation. Follower plates fitted with bleed air valves. Pump yoke is air-operated with a raise/hold/lower air valve. No electric controls so pump can be operated in almost any environment including confined spaces. |

The Model C is a portable unit for pumping 1:1 ratio high viscosity two component epoxies from 5-gallon pails. It uses 2 synchronized air-driven piston pumps to deliver high volumes of precisely mixed paste for patching, surface sealing, large crack filling, or bolt/dowel/rebar grouting. It allows the contractor a freer choice of gel times and viscosities without worrying about batch mixing and wasted material. Flexible rubber follower plates clean the pails so waste is minimal. Sure beats buying a gazillion cartridges on large jobs! One of our contractors estimates that the Model C is 4 times faster than cartridges.
