VISCOUS LIQUID PUMPS

VISCOUS LIQUID PUMPS / SINGLE SOLENOID
MODEL VERR / VSESAT (AUTOMATIC RETURN)
This model incorporates a 4-way Single Solenoid Doubled
Bleed Pilot Valve. A momentary (NOT continuous)
electrical contact is required to move the piston its full stroke.
Upon reaching its FULL stroke, the piston will automatically
return to its original position.
This model is supplied with the piston normally retracted
(electrical contact will extend the piston)
The standard solenoid operator, is the AAS splice box housing.
Due to internal construction and application requirements,
there can be a loss of approximately 1/8" to 1/4" of stroke.
Voltages: 12,24,120 & 240/60 and 6,12 & 24VDC are
standard.

VISCOUS LIQUID PUMPS / DOUBLE SOLENOID
MODEL SDS / VDST
This model incorporates a 4-way Double Solenoid Pressure
Pilot Valve. A momentary or maintained electrical contact
applied to one solenoid will move the piston its full stroke.
The piston will remain there under pressure until the other
solenoid is energized, which will cause the piston to
return to its original position. If a maintained contact is
employed, the first solenoid must be de-energized before
the other is energized.
The standard solenoid operator, as shown is the AAS
splice box housing.
Voltages: 12, 24,120 & 240/60 AC and 6, 12 & 24VDC are standard.

Explosion Proof, NEMA 4 & 6 or Allenair's standard electric operators(see Allenair.com) may be used on Allenair's air operated pumps, direct acting pumps and industrial dispensing pumps to control all of Allenair's self priming pumps. Self contained bleed screws control the speed of Allenair's piston pumps aiding in the positive displacement pumps output. Because of wide range of Allenair power pumps cylinder bore sizes(1-1/2" to 4"),heavy viscous liquid pumps have the power for the precision dispensing of peanut butter, heavy crude oil, toothpaste or lard.
