HD2-200
High
pressure pump for preparative LC.
The HD-200 pump is a
dual piston precision metering pump designed for HPLC as well als
MPLC. The pistons are mounted parallel. The housing of the check valves
and the liquid ends are manufactured out of stainless steel 1.4571
or PEEK. The pistons as well as the check valve seats are made of
saphire, while the material of the ball is ruby. the PTFE pump seal
contains a little spring, shich helps to seal the inner flange around
the piston. The optimised design ensures virtually pulse-free and
stable solvent delivery.
The flow rate of the pump can be varied by the rotation speed of the
pump motor. The maximum flow rate (depending on the pump model) is
1 l/min. The operating pressure of the pump is continuously measured
by an inductive pressure sensor and minitored on at the bright LED
and LCD display on the front panel.
The pump can be externally controlled. A computer jack allows flow
rate rontrol
(0-10V, 0-20 mA) for applications such as high pressure gradient operation
together with a second pump and a mixing chamber. The pressure can
be recorded by a 0-10 V signal. Pressure limits can be selected to
protect the system during unattended operation. Also in PEEK.

The HD 2-300
is a precision metering pump designed for high performance
liquid chromatography (HPLC).
The pistons and the valve seats are made of sapphire, the valve balls
of ruby. The valve-casing and the pump heads are made of stainless
steel or PEEK.
The pressure is recorded by a sensor and then displayed in 'psi'.
A minimum and maximum pressure can be set for security shut off.
The flow range is controlled by the motor speed. The pump can be controlled
externally by RS 232 or anlag 0-10V DC / 0-20mA.Also in PEEK.

This Unique pump features
10 separate heads which are combined in 2 blocks
per 5.
The both blocks are combined with the mechanics in that kind that
a 5 channel double head pump emerges from connecting the blocks.
The pump heads are from stainless steel 1.4571, the vlaves assemble
from ruby and sapphire (ceramics). The pistons are either from sapphire
or ceramics, independent of model of the pump heads.
For controlling of the pump a processor controlled DC drive is beeing
applied. The external controll is versatile, whether analogue (0-10V,
0-20mA) or digital (RS232).
For monitoring 2 more signals (flow and operation) are available.
The massive designed mechanics allow a high operation pressure. The
pressure information in the lower table concerning to one channel.
At the 10ml version 10 channels with 725 psi per can be operated e.g.
