New Harvard Peristaltic Pumps
R. Pelletier, September 2012
What is a Peristaltic Pump
• Positive displacement pump
• Fluid is contained within a flexible tube
fitted inside a circular pump casing
• A rotor with a number of "rollers",
attached to the external circumference
compresses the flexible tube.
• As the rotor turns, the part of tube
under compression is pinched closed
forcing the fluid to be pumped to move
through the tube.
• Flow Rate depends on tubing I.D.,
length of tubing, and motor rpm.

Quick Start Menu
Pump Settings
Settings allow for interchangeable drives/heads on one control unit
Tubing Selection
Icon indicates combined number of
channels for flow rate. For example, P70 with 2 channels selected will have
maximum flow of 140 mL/min
Built in library allows for the
selection of HA supplied tubing or
tubing of the customer’s choice
Timed or Volume Dispense
Set Dispense by time or Volume
Method Profiles
Methods may be linked as well as stored
Advanced Options allow for methods to be tied
to I/O events and time delays
Calibration
Pump calibration may be for single channel, or combined
flow from multiple channels
Run Screen
Method Preview

Competition - 2 General Types of Peristaltic Pumps
• Type 1 - Analog (similar to HA MP-II)
• Sell for $500 - $1,200
• Older design electronics
• Flow rates are approximate
• No modern features
• Difficult to calibrate
• Limited I/O capability
Competition
• Type 2
• Digital – Sell for $1,500 to $4,000
• Advanced electronics
• Allow for calibration and direct setting of flow
Competition
• Main Competitors – Digital
• Cole Parmer
• Ismatec/Reglo
• Watson Marlow
• Wheaton Scientific
Competition
• Cole Parmer mainly 1-2 channel systems
• Ismatec/Reglo multichannel systems, but low level
electronics. Sold through distributors.
• Watson Marlow mainly OEM supplier of pump heads.
Wheaton uses WM heads.
Competition
• Compete on capabilities and application –
• Start with number of channels and flow rates
• Digital capabilities
• Product Configuration options
Know the competitive product and be sure you are making a valid
comparison.
Competition
• HA Pricing is competitive
• For P-70, HA ILP=$2,990, Competitive range is $2,900-
$3,200.
• For P-230, HA ILP=$3,162, Competitive range is $3,000-
$3,300
• For P-1500, HA ILP=$2,474, Competitive Range is
$2,200-$2600
