CH, CHNGeneral description
IntroductionThe Grundfos CH and CHN pumps are non-self-priming, horizontal, multistage centrifugal pumps.
Pump and motor are integrated in a compact and user-friendly design fittet to a base plate making the pumps suitable for installation in compact systems.
CH and CHN pumps have many incorporated advan-tages such as those mentioned below.
Worldwide usage • Different certificates and approvals like UL/CSA for
America and Canada.• Different voltage and frequency combinations.• State-of-the-art shaft seal materials (silicon carbide
SiC-G) offering these benefits:- high wear resistance and long operating times- reduced risk of sticking if the liquid contains glycol- improved dry-running properties due to the graphite content of the SiC.
Electro-coated cast iron parts• High corrosion resistance.• Better efficiency because of smooth surfaces.
Customized solutionsSee “List of Variants” on page 36.
• Motor adaptation. • Pump body modifications.
MaterialsCH: Chambers and all moving parts in contact with the pumped liquid are made of stainless steel. Discharge chamber, suction chamber and base plate are painted non-gloss black.
CHN: Discharge chamber, suction chamber, base plate and all parts in contact with the pumped liquid are made of stainless steel.
The pump is CE-marked.
ApplicationsThe CH and CHN pumps are designed for small domestic and industrial systems.
Applications• Liquid transfer and circulation of liquids within light
industry and farming• Pressure boosting in single-pump and multi-pump
booster systems• Domestic water supply• Cooling systems• Air-conditioning systems.
Pumped liquidsCHThin, clean, non-aggressive and non-explosive liquids without solid particles or fibres.
CHNThin, clean, slightly aggressive and non-explosive liquids without solid particles or fibres.
Operating conditions
*Lower temperatures are possible. See Lists of variants on page 36.

CH, CHNConstruction
PumpThe CH, CHN pumps are non-self-priming, horizontal, multistage centrifugal pumps with mechanical shaft seal and through-going pump-motor shaft. The pumps have axial suction port and radial discharge port and are mounted on a base plate. All movable parts in contact with the pumped liquid are made of stainless steel.
EPDM or FKM O-rings are available as standard. See pipe connections in the table.
MotorThe pump is fitted with a TEFC (totally enclosed, fan-cooled), squirrel-cage Grundfos motor.
The single-phase motors are supplied with a built-in thermal relay to IEC 34-11, TP 211 (slow overload as well as locked rotor). The motors require no further motor protection.
The three-phase motors do not incorporate thermal protection and therefore require external motor protection in accordance with local regulations.
The sound pressure level of the pump is lower than the limiting values stated in the EC Council Directive 98/37/EC relating to machinery.
Frequency converter operationMost three-phase motors can be operated with a frequency converter. See Lists of variants on page 36.

CH, CHNCurve charts
Curve conditionsThe guidelines below apply to the curves on the following pages.
• Tolerances according to ISO 9906, Annex A.• The bold curves state the recommended
performance range.• The thin curves are only intended as a guide.• The curves must not be used as guarantee curves.• All curves are based on measurements at:• 1 x 230 V, 50 Hz• 3 x 400 V, 50 Hz• 1 x 220 V, 60 Hz• 3 x 380 V, 60 Hz.• When the motor is running at the lowest or highest
rated voltage, the pump performance will usually vary by ± 0.5 - 1.0 m at a given duty point.
• Specific minimum performance requirements necessitate individual measurements.
• The measurements have been made with airless water at a temperature of 20 °C (~70 °F).
• The conversion between head H (m) and pressure p (kPa) applies to a water density of ρ = 1000 kg/m3.
• The curves apply to a kinematic viscosity of υ = 1 mm2/s(1 cSt)

CH, CHNPumped liquids
Pumped liquidsThin, non-explosive liquids, not containing solid particles or fibres. The liquid must not chemically attack the pump materials.
When pumping liquids with a density and/or viscosity higher than those of water, oversized motors must be used, if required.
Whether a pump is suitable for a particular liquid depends on a number of factors of which the most important are the chloride content, pH value, temperature and content of chemicals and oils.
Please note that aggressive liquids (for instance seawater and some acids) may attack or dissolve the protective oxide film of the stainless steel and thus cause corrosion.
List of pumped liquidsA number of typical liquids are listed below.
Other pump versions may be applicable, but those stated in the list are considered to be the best choices.
The table is intended as a general guide only and cannot replace actual testing of the pumped liquids and pump materials under specific working conditions.
The list should, however, be applied with some caution as factors such as concentration of the pumped liquid, liquid temperature or pressure may affect the chemical resistance of a specific pump version.
Safety precautions must be made when pumping dangerous liquids.
Notes
a May contain additives or impurities which can cause shaft seal problems.
b The density and viscosity may differ from those of water. Consider this when calculating motor and pump performance.
c In order to avoid corrosion, the liquid must be free of oxygen.
d
Flammable or combustible liquid.Safety precautions must be considered to ensure safe handling of flammable liquids. Handling the liquid above the flashpoint and/or boiling point will require the greatest restrictions. A seal-less pump may be required. Contact Grundfos.
e Risk of crystallization/precipitation on the shaft seal.f If oil residues are present, EPDM cannot be used.

Variants
Lists of variantsAlthough the Grundfos CH, CHN product range offers a number of pumps for different applications, customers require specific pump solutions to satisfy their needs. Below are the options available for customizing the CH. Contact Grundfos for further information or for requests other than the ones mentioned below.
Motors
Shaft seals
Connections and other variants
Certificates and nameplates
PumpsMotor with thermal protection
Grundfos offers motors with bimetallic thermal switches or temperature-controlled PTC sensors (thermistors) in the motor windings.
Oversize motor
In installations where one of the conditions mentioned below is present, the motor size must be evaluated to make sure there will be no risk of overload. • Ambient temperatures above 55 °C.• Liquid temperatures below 0 °C.• Installation at an altitude of more than
1000 metres above sea level • Use of glycol or other high-viscous liquids.Alternative motors are available on request.
Dual-voltage motors 50/60 hz
In some cases the standard product can run at dual voltage and frequency. If the standard product cannot be used for dual voltage, a bigger motor can very often be used instead.
Use of external frequency converter
For most three-phase CH, CHN pumps a frequency converter can be used. Single-phase motors are not suitable for frequency converter operation. In many cases where an external frequency converter is used it is necessary to protect the motor against voltage peaks higher than 650 V (peak value). In these cases it is often less expensive to ask for phase insulation in the pump than use a filter such as an LC filter. Grundfos offers pumps with phase insulation to protect the pump against voltage peaks up to 1000 V (peak values). This is a customized version, and the supplier of the frequency converter must be consulted.
Harting plug Harting plugs are available for easier replacement of pumps.
Terminal box position Other terminal box positions are possible.
CVBV, CVBE, AQQE, AQQV are standard for CH, CHN pumps.Shaft seals with FFKM or FXM O-ring material are recommended for applications where the pumped liquid may damage the standard O-ring material.
Pipe connections NPT and Rp threads are available.
Certificates
Certificate of compliance with the orderTest certificateInspection certificateStandard test report
Extra nameplate
UR-marked motorIf the UL-listed product according to UL778 is not available, a pump with UR-marked motor according to UL1004 can be offered as an alternative.
Low-temperature pump
Exposed to temperatures below –20 °C, coolant pumps may require neck rings with a different diameter or without a neck ring in order to prevent impeller drag. If neck rings are removed, a reduction of the head must be expected. In some extreme cases, –25 °C cold liquids can be pumped by a CH pump. Contact Grundfos.
