DISPENSING & TRANSFER PUMPS

Allenair Manufactures Dispensing & Transfer Pumps

Allenair’s pneumatic-hydraulic-air-water or gas operated, direct acting, Positive Displacement Piston Pumps are used where precision metering and dispensing of viscous and acidic liquids is top priority. Allenair’s Self-Priming and automatic Reciprocating Metering pumps may be used in Volume Metric Industrial Dispensing applications, or as Sanitary or Acid transfer pumps. Allenair’s wide range of Power Pump bores and strokes will allow the pumping and dispensing of very heavy viscosities such as Lard, Crude Oil, Peanut Butter, Vinyl Sealants, Syrups or Food Batters. Pumps are explosion proof.



  • For the pumping and transfer of most liquids.
  • Accurately dispense various food products and chemicals.
  • Pumps can be made in a number of variations, which can include different seal and pump materials depending on application requirements.

DISPENSING & TRANSFER PUMPS
APPLICATION IDEAS


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.

PUMPING CORROSIVE LIQUIDS.

Used to pump deionized water, the photograph to the right
depicts an EVTP model pump with an all stainless steel
pump chamber, utilizing a VCR automatic reciprocating
Valve in Head drive cylinder.

DISPENSING FOOD PRODUCTS.

Used to dispense lard or high viscosity liquids the photograph
to the right depicts an ALL 300 Series Stainless Steel SSETP
model pump. This pump utilizes an SA adjustment rod to produce
a variable displacement chamber, with exceptional repeatability.

DISPENSING PETROLEUM BASED PRODUCTS.

Used to dispense lubricating oil, the photograph to the right
depicts an EVTP model pump. This pump utilizes a VSAT
valve option to dispense a fixed volume of oil while maintaining
the ability to adjust that volume using the SA adjustment rod.

DRIVE CYLINDER VALVES

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.





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.






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.

DRIVE CYLINDER VALVES

CONTINUED

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.






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.






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"


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.





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

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



Temperature ratings and chemical compatibilities shown below are for general comparisons. See specific O-ring
presentations for exact specifications. NR=Not recommended.

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
