Specifications

8" Flat Vacuum Cup with ABS Handle

pump style suction cup lifter

PP plastic handle and rubber pad.

Features:

  1.Lightweight, heavy duty handle made of rustproof ABS.

  2.Fast attachment on smooth, nonporous flat surfaces.

  3.Red-line indicator warns user of any significant vacuum loss.

  4.Check valve allows repumping without loss of remaining vacuum.

  5.Release valve lever permits quick and complete release.

  6.Easily replaceable handle/release valve and plunger.

  7.Supplied with protective carrying case. 

This lifting device has a 8'' diameter rubber suction pad on a metal mount and handle. It is designed to lift non porous smooth flat surface panels in the parallel or perpendicular direction of the panel surface and has a maximum load capacity of 57 kg (125 lbs). A manual air pump evacuates the air from the rubber pad and a red indicator bar on the plunger allows you to monitor the status of the vacuum seal. To release, simply press the vacuum release valve. The lifter comes in a plastic carrying case. Lifter sold individually.                                                                                    

HOW THEY WORK

Vacuum cups employ the force of atmospheric pressure to grip a surface: When a vacuum exists between the cup and the surface on which it is attached, the weight of Earth’s atmosphere holds the cup in place with incredible force. Unlike suction cups that produce a vacuum as they pull away from the surface, vacuum cups use a hand-actuated pump to efficiently remove air from between the rubber pad and the attaching surface–thus creating a much more reliable hold. Because the full face of the pad is brought into contact with the surface, distortion is reduced, allowing the cup to be used on materials of almost any thickness with little risk of damage.

Each vacuum cup’s pump features a plunger with a red line, which serves as a vacuum indicator. This safety device is recognized as one of the most reliable warning systems available. A few strokes of the plunger evacuate the vacuum pad, causing it to seal securely to the attaching surface. When the cup is attached completely, the plunger stops moving and the red line is hidden within the pump. A visible red line indicates that air has leaked back into the pad, making vacuum insufficient to use the cup. However, if the red line becomes visible while the cup is in use, a check valve allows the user to repump the cup without losing the remaining vacuum.

A release mechanism allows air to refill the evacuated space, so that the vacuum cup detaches completely, with no dangerous after-stick. N-Series cups are released by pressing the valve release lever located opposite the plunger, while other cups are released by lifting on the release tab near the edge of the pad. 

PLS note:

In the button there is red warning line, not available to lift when red line is visible. For object which is bigger and heavier, need to use 2 or more suction cups to work.
