Description:

The Allenair pumps are designed around our tandem cylinder design joining two cylinders together with a common head and rod. The total pump unit is divided into two sections; the drive section and the pump section. By utilizing a four-way valve to operate the drive cylinder, the common rod and pump piston will move in unison, creating suction on the up stroke and pressure on the down stroke. An example of this action is that of a syringe.

SINGLE SOLENOID

MODEL SVSR / VSST
This model incorporates a 4-way Single Solenoid Pilot Valve, air return. A maintained electrical contact is required to move the piston its full stroke. Breaking the electrical contact returns the piston to its original position. This Model is supplied with the piston normally retracted (electrical contact to extend piston) The standard solenoid operator is the AAS splice box housing. Voltages: 12, 24,120 & 240/60 AC and 6, 12 & 24VDC are standard.

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.

SINGLE PILOT

MODEL APSRR / VAPSRT
This model incorporates a 4-way Single Pressure Pilot Valve. A continuous pilot pressure applied to “IN” side of valve will move the piston its full stroke. When the pilot pressure is released, the piston will return to its original position. Pilot pressure is normally supplied through a 3-way N.C. Valve. Model is supplied with the rod normally retracted (pilot pressure to extend rod) pilot pressure must be at least 75% of the operating pressure.

Precision Dispensing Pumps

SINGLE PILOT

MODEL VARR / VSAT (AUTOMATIC RETURN)
This model incorporates a 4-way Double Bleed Pilot Valve. A momentary (NOT continuous) actuation of a Bleeder Valve 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 rod normally retracted (manual bleed to extend rod)
Due to internal construction and application requirements, there can be a loss of approximately 1/8” to 1/4” of stroke. Bleeder Valve Model BV100 is supplied on these models

Precision Dispensing Pumps

DOUBLE PILOT

MODEL AP / VAPT
This model incorporates a 4-way Double Pressure Pilot Valve. A momentary or maintained pilot pressure applied to one side of the valve will move the rod its full stroke. The piston will remain in that position under pressure until a pilot pressure is released and applied to the other side, which will cause the piston to return to its original position.
If a maintained pilot pressure is applied, it must be released before the other pilot pressure is applied. Pilot pressure must be at least 25% of the operating pressure.

AUTOMATIC RECIPROCATING

MODEL VCR (NOT AVAILABLE WITH “SA” OPTION)
This model incorporates a 4-way Double Bleed Pilot Valve. By means of Built-in Bleeder Valves and internal Cam Bosses.
This unit will automatically reciprocate as soon as air pressure is applied. It is recommended that a shut-off valve be mounted in the inlet line. Due to internal construction and application requirements, there can be a loss of approximately 1/4” to 1/2” of stroke. Minimum stroke available is 1”

Metering Pumps

MANUALLY OPERATED

The following 2 models incorporate a 4-way Manual Valve.


MODEL VH / VHT
This model requires manual operation
of the lever to both extend and
retract the piston.

Metering Pumps

MODEL VHSRR / VHSRT:

This model is lever operated
to extend the normally retracted piston. The valve is
equipped with a built-in spring return which automatically
returns the rod when lever is released .

MISCELLANEOUS INFORMATION

ALLENAIR PUMP DISPLACEMENTS VOLUMES


Drive Cylinder Air Consumption

This chart is used for calculating the air consumption of the pump drive cylinder to
determine the total volume of air required to meet a given cycle rate. The values shown
are for 100 P.S.I.


Example:

Total air consumption of a 2" bore drive cylinder with a 6" stroke operating at 10 cycles
per minute (20 strokes per minute):
6" Stroke x 0. 0142 (SCFM Inch Stroke) = 0.0852 SUM
0.0852 SCFM Stroke x 20 Strokes Per Min. = 1.704 SCFM


PUMP CURVE AT MAXIMUM PISTON VELOCITY

These figures are based on the maximum piston velocity the drive cylinder may
achieve pumping on one side only with a no load condition operating at 100
P.S.I for one minute at the Maximum cycle rate for the VCR cylinder model.

General Properties of Allenair's Seal Materials

presentations for exact specifications. NR=Not recommended.

VISCOSITY CHART


Pressure to Head Conversion formula

Liquids have specific gravities typically ranging from 0.5 to 1.8. Water is the benchmark with a specific gravity of 1.0. this benchmark and the resultant calculations are considered to be in "feet absolute." Head (ft) = Pressure (PSI) X 2.31/ Specific Gravity This formula is based on the fact that one foot of water exerts .4333 lbs of pressure at one foot. This converts to one lb. of pressure at 2.31 ft.


  • sg. = specific gravity
  • pressure = pounds per square inch
  • head = feet

Pressure = head x sg.
2.31


Head = pressure x 2.31
